IconVault is a free library of 421,020 icons across 239 collections - every set from Material Symbols and Lucide to brand logos, emoji and flags, plus our exclusive in-house IconVault Originals set. Everything is served from our own edge network, so icons load instantly with no rate limits on browsing.

• Browse all sets on the App page - scroll, or jump to any collection from the sidebar.
• Search 421,020 icons by keyword, or use AI search to describe what you need in plain words.
• Click any icon for a detail view with copy-ready code in every format.
• Build a full logo + favicon kit in the Logo Builder tool.

The search box searches icon names across all 239 collections at once. Results stream in as you type, ranked by relevance.

AI search

Describe the icon you need instead of guessing its name - e.g. “a dog wagging its tail” or “download arrow in a circle”. AI search understands intent, style and context, then returns the closest matches from the library.

• Works in plain English - no keyword guessing.
• Great for abstract concepts: “teamwork”, “fast delivery”, “secure payment”.
• Combine with collection filters to stay inside one icon family.

Click any icon to open its detail modal. From there you can preview it at any size, on light and dark backgrounds, and copy production-ready code in one click.

Formats

• SVG - clean vector markup, ready to paste anywhere.
• React / Vue - framework components with props for size and color.
• Tailwind - utility-class snippet using currentColor.
• PNG - raster export at any size for docs and decks.
• Data URI - embed tiny icons directly in CSS.

Collections group icons into named packs per project: a brand kit, a dashboard set, a marketing pack. They sync across your devices when you are signed in, and you can export the whole set as SVG in one download.

Workflow

• Open the Collections page and create a collection with a name.
• Add icons from anywhere: the multi-select toggle on the icon browser, or the add button on an icon's detail view.
• Open a collection to preview every icon together, remove ones you don't need, and download the full set as a ZIP of SVGs.

Choosing between three similar arrows? The Compare page puts candidate icons next to each other at real sizes, on light and dark surfaces, so you can judge them the way users will actually see them.

• Add icons to the comparison from the icon browser or a detail view.
• Toggle sizes and backgrounds to see how each candidate holds up at 16px in a tab versus 48px on a landing page.
• Pick the winner and copy its code straight from the comparison.

Bring your own SVGs into the same workspace as the open sets. Uploaded icons are cleaned, previewed at real sizes, and ready to export or share with your team - your private icons sit alongside the library without mixing into it.

• Open the Upload page and drop your .svg files.
• Each file is validated and cleaned on import, then previewed at multiple sizes so you can spot broken paths before you use them.
• Your uploads appear in your own private section and export exactly like library icons.

Design Tokens turns a saved icon set into tokens your codebase can consume directly: CSS custom properties, a JSON manifest, a Tailwind plugin, or typed TypeScript constants.

• Build a collection of the icons your project uses.
• Open Design Tokens, pick the collection and the output format.
• Copy the tokens into your project - CSS variables for stylesheets, the Tailwind plugin for utility classes, or TypeScript constants for component libraries.

Searched everything and the icon you need does not exist? Tell us what it should look like. We track requests, point you at the closest existing matches, and push popular ones upstream to the icon sets.

• Open the Request page and describe the icon: what it depicts, where you will use it, and any style notes.
• Check the near matches we suggest first - the icon you want may already exist under a different name.
• Popular requests get priority, and Pro members' requests jump the queue.

Drop a PNG, JPG, WebP or GIF and get a true vector SVG back - shapes are traced and curves fitted in your browser, so nothing is uploaded. You see an interactive preview before downloading.

Controls

• Colors (2–16): fewer colors = cleaner, smaller SVGs. Pro unlocks up to 16.
• Detail slider: higher detail keeps fine edges but grows the file.
• Remove background: drops white/transparent backdrops for clean logo traces.

Limits

5 free conversions per visitor per day, no account needed. Pro (from $19/year) unlocks unlimited conversions, 16-color traces and batch ZIP export of up to 10 images.

Design the social preview cards shown when your links are shared on X, LinkedIn, Facebook, Slack and Discord. Presets: 1200×630 Open Graph, 1200×600 X card, 1200×627 LinkedIn, 1080×1080 square, 1080×1350 portrait, 1080×1920 story.

Workflow

• Type your headline and subheadline - text auto-shrinks and wraps to fit.
• Pick a Google Font, a gradient/solid/photo background, and an optional pattern overlay.
• Add a badge pill, upload your logo, and drop any of 421,020 icons onto the card.
• Export crisp PNG or JPG at 1x or retina 2x - or copy the image to your clipboard.

Limits

5 free PNG exports per visitor. Pro unlocks unlimited exports and every template.

Capture pixel-perfect screenshots of any public URL - desktop (1280×800), laptop (1440×900), tablet (768×1024) and mobile (390×844) viewports. No extension or install needed.

• Paste the URL, pick a viewport, hit Capture - PNG in seconds.
• Use it for portfolios, competitor teardowns, bug reports and documentation.
• Only publicly reachable URLs can be captured (no localhost or login-walled pages).

Scroll Video

The Scroll Video tab records a real 5-second scrolling video of any page. Pick a format - MP4, WebM or GIF - and an aspect ratio: vertical 9:16 for Reels/Stories, square 1:1 for feeds, horizontal 16:9 for YouTube.

• The page pre-scrolls twice before recording, so lazy-loaded images and sections appear fully loaded.
• One smooth ease-in-out glide from top to bottom - preview in-page, then download.
• WebM and GIF are converted privately in your browser; the MP4 comes straight from the recording.

Limits

5 free captures per visitor (including 2 free full-page captures) plus 5 free scroll videos. Pro unlocks unlimited captures, unlimited videos, unlimited full-page screenshots and HD retina output.

Shrink PNG, JPG and WebP images by up to 80% - entirely in your browser. Your files are never uploaded, so client work stays private.

Workflow

• Drop up to 20 images at once.
• One click - the tool automatically picks the smallest format: transparent images become WebP, everything else becomes JPEG. Original dimensions are always kept.
• Drag the quality slider if you want smaller files or higher fidelity.
• Every file shows before/after size and % saved; download individually or as one ZIP.

Limits

5 free compression runs per visitor. Pro unlocks unlimited runs and batch ZIP downloads.

• Drop any of 421,020 icons onto the canvas as a sticker, left or right.
• Tune text and stroke colors, then export a crisp PNG ready for YouTube Studio.

Limits

5 free thumbnail exports per visitor. Pro unlocks unlimited exports and every template.

The Tools hub is home to 579 free online tools across 17 categories: image tools, developer utilities, text tools, converters, generators and more. Every tool runs in your browser, so your files never leave your device.

Finding a tool

• Use the big search bar at the top of the Tools page - it filters all 579 tools as you type.
• Browse by category: click any of the 17 category chips, or open a category page to see every tool inside it.
• Deep links work too: a search like /tools?q=qr jumps straight to matching tools.

How tools work

• Each tool page has the same layout: the tool itself up top, then About, FAQs and related tags below.
• Free visitors get 5 uses per tool, no account needed. Usage is tracked per tool on your device.
• Pro (from $19/year) unlocks unlimited runs of every tool.
• Tags under each tool are clickable - they lead to related tools and icon searches.

The Logo Builder turns any library icon into a complete brand mark: pick an icon, style the tile, add a wordmark, then export everything you need to ship.

Workflow

• 1. Search the icon panel and click an icon to place it on the canvas.
• 2. Pick a style preset - or tune background, gradient angle, corner radius, rotation and opacity yourself.
• 3. Add effects: drop shadow, border stroke, and an optional wordmark underneath.
• 4. Hit Shuffle for instant inspiration.
• 5. Export PNG (1024px) or SVG free - or grab the full logo kit.

Full logo kit (Pro)

The ZIP kit includes favicon-16/32, apple-touch-icon (180), Android icons (192/512), the vector SVG, a ready site.webmanifest and an HTML <head> snippet - everything a developer needs to install your logo in one go.

Select multiple icons anywhere in the app (use the multi-select toggle) and download them together as a ZIP of SVGs - or add PNG renders at 64, 256 and 1024px.

• Free accounts get 7 bulk downloads - plenty to try the workflow.
• Pro (from $19/year) unlocks unlimited bulk downloads.
• ZIPs are generated in your browser; your selections never leave your device.

Every icon is reachable over a simple REST API - perfect for scripts, build tools and internal dashboards. You can start without any account: keyless calls work under per-minute IP limits.

curl 'https://iconvault.site/api/iconify/search?query=shopping%20cart&limit=5'

curl 'https://iconvault.site/api/icon/mdi/cart.svg'

curl -X POST 'https://iconvault.site/api/icons' \
  -H 'Content-Type: application/json' \
  -d '{"icons": ["mdi:cart", "lucide:heart"]}'

curl 'https://iconvault.site/api/iconify/collections'

Getting an API key

• Go to the API Access page and sign in.
• Give your key a name (e.g. "my-build-script") and click Generate.
• Copy the key immediately - it is shown only once. Store it somewhere safe, like an environment variable.
• You can revoke a key any time from the same page; revoking takes effect instantly.

Using your key

Send the key as the x-api-key header (or as an Authorization: Bearer token). One JSON request with your key counts as one unit against that key's monthly quota.

curl 'https://iconvault.site/api/iconify/search?query=arrow&limit=20' \
  -H 'x-api-key: YOUR_KEY_HERE'

Limits and errors

• Keyless: 120 searches, 240 single-icon fetches and 120 batch calls per minute per IP.
• Keyed: 1,000 calls per 30-day window per key, with no per-minute cap. Repeat SVG fetches served from the edge cache are free and do not count.
• 401 Invalid API key: the key is wrong, revoked, or missing where one is required. Check for typos and extra spaces.
• 429 Too many requests: you hit a per-minute IP limit (keyless) or your key's monthly quota is exhausted. Wait a minute, or generate a fresh key next month.

The IconVault CLI brings the icon library into your terminal: search 421,020 icons and download them as optimized SVGs without leaving your workflow. It is free, open source, and has zero dependencies (Node 18+ only).

npm install -g @iconvault/cli

npx @iconvault/cli search "shopping cart"

Commands

iconvault search "shopping cart"
iconvault search arrow --limit 5

iconvault add mdi:cart
iconvault add lucide:heart --out ./src/icons

iconvault --help
iconvault --version

Options

• --limit N: number of search results (default 20, max 999).
• --out DIR: output directory for add (default ./icons, created if missing).
• --api URL: point at a different API base (default https://iconvault.site).

Using an API key (optional)

Without a key you share the public per-minute IP limits. Set your key once and the CLI sends it automatically, giving you 1,000 calls a month with no per-minute cap.

export ICONVAULT_KEY=YOUR_KEY_HERE
iconvault search "arrow"

If your own product lets users pick icons (a dashboard, a CMS, a docs site), you do not have to build search and previews yourself. Paste one script tag and a live IconVault picker appears on your page.

Is IconVault really free?

Yes - browsing, searching, copying and single downloads are free forever, and every tool gives you 5 free uses per day. Pro is an optional paid plan (from $19/year) that unlocks unlimited everything.

Can I use the icons commercially?

Every collection keeps its original open-source license (MIT, Apache 2.0, CC0 and similar). The license is shown on each collection page - brand logos additionally carry trademark restrictions, so check before using those in a product.

Why do I need an account for the logo kit?

The kit is a Pro feature tied to your Pro plan, so we need to know who you are. Browsing and single exports never need an account.

Do you add new icon sets?

Yes - the library tracks Iconify releases, so new collections and icon updates flow in regularly. Pro members can request priority additions.

The SVG to PNG Converter rasterizes any SVG into a crisp PNG at 256, 512, 1024 or 2048px on the longest edge, or exports all four sizes as one ZIP. Everything happens in your browser - the SVG is drawn to a canvas locally and never uploaded anywhere.

How to use

• Paste your SVG markup into the text area, or upload an .svg file.
• Pick an output size - 256, 512, 1024 or 2048px. The aspect ratio is read from the SVG's viewBox so icons keep their proportions.
• Click Convert to PNG to render a live preview, then download that size.
• Need every size? Click All sizes ZIP to export 256 → 2048px in one download - ideal for favicon and app-icon sets.
• Use the 1x–4x scale presets, type a custom W×H, or pick a background: Transparent (default), White, Black, or any custom color for slide/print-safe exports.

Free plan: 5 conversions per tool, no account needed. Pro (from $19/year) unlocks unlimited conversions across all tools.

The SVG Optimizer trims bloat from SVG files - comments, redundant whitespace and excess decimal precision - so they load faster. Design-tool exports from Illustrator, Figma and Inkscape typically shrink 20–60% with zero visual change.

How to use

• Paste your SVG markup into the text area.
• Pick your options: decimal precision (0–4 places), strip metadata/title/desc, remove empty or hidden elements, drop unused IDs and data-* attributes. Then click Optimize SVG.
• Check the before/after byte counts and the percentage saved.
• Copy the optimized markup or download it as an .svg file.

Free plan: 5 optimizations per tool, no account needed. Pro (from $19/year) unlocks unlimited runs across all tools.

The SVG to JSX Converter turns raw SVG markup into framework-ready components: JSX, typed TSX, Vue or Svelte. Kebab-case attributes are mapped to camelCase (stroke-width → strokeWidth, class → className) and tags are self-closed, fixing the two things that break SVGs pasted straight into React.

How to use

• Paste your SVG markup (it must contain an <svg> tag).
• Pick the output tab: JSX, TSX, Vue or Svelte.
• Click Convert - switching tabs re-converts instantly from the same input.
• Copy the code and paste it into your project. The TSX output spreads props onto the root element, so className, style and onClick work out of the box.
• Extras: a TypeScript toggle for typed props, Icon mode (strips width/height → 1em sizing so icons scale with font-size), an editable component name, and a {...props} spread toggle.

Free plan: 5 conversions per tool, no account needed. Pro (from $19/year) unlocks unlimited conversions across all tools.

The SVG to Data URI generator encodes your SVG into a data:image/svg+xml URI for use as a CSS background-image or an HTML <img> src. The output is URL-encoded, so # in fill colors becomes %23 - the fix for the most common reason hand-made SVG data URIs fail in Firefox.

How to use

• Paste your SVG markup into the text area.
• Click Generate data URI.
• Copy the CSS background-image rule or the HTML embed snippet - both are ready to paste. The format selector also gives you the raw URI or a CSS mask pair.
• Decode mode reverses it: paste any data URI (base64 or URL-encoded) and get the original SVG back - handy when debugging someone else’s CSS.
• Check the data URI byte length to decide whether a data URI or a separate file is the better choice for that graphic.

Free plan: 5 generations per tool, no account needed. Pro (from $19/year) unlocks unlimited runs across all tools.

The SVG Sprite Generator merges multiple SVGs into one sprite.svg file, where each icon becomes a <symbol> with its own id and viewBox. One cached file then serves your whole icon set, referenced anywhere with <svg><use href="sprite.svg#icon-name"></use></svg>.

How to use

• Add an entry per SVG: give it a name (this becomes the symbol id) and paste its markup.
• Use Add another SVG for as many icons as you need; remove entries you don't want.
• Click Generate sprite. Each SVG needs a viewBox - entries without one are skipped with a warning.
• Download sprite.svg, or copy the sprite markup. Every symbol now has its own Copy-usage button with a ready <svg><use href="#id"/></svg> snippet - and a currentColor toggle makes the whole sprite recolorable via CSS.

Free plan: 5 sprite generations per tool, no account needed. Pro (from $19/year) unlocks unlimited runs across all tools.

The Image Resizer changes the pixel dimensions of up to 10 images at once, entirely in your browser. Scale by percentage, type exact dimensions, or lock the aspect ratio - then export to PNG, JPG or WebP and download individually or as a ZIP.

How to resize

• Drop up to 10 images onto the upload zone (PNG, JPG, WebP).
• Drag the scale slider, or type an exact width × height to override it.
• Keep “lock aspect ratio” checked and fill only one side to scale proportionally.
• Choose the output format and click Resize, then download each file or the ZIP.

Limits: 10 images per run, 8192px max per side. Every visitor gets 5 free resizing runs per day - IconVault Pro (from $19/year) unlocks unlimited runs of every tool. Your files never leave your device.

The Favicon Generator renders all five standard favicon sizes - 16, 32, 180, 192 and 512px - from any of 421,020 library icons or an image you upload. Every individual PNG download is free.

How to generate favicons

• Search the library and pick an icon, or upload your own image.
• Click “Generate favicons” - all five sizes render instantly in your browser.
• Download any PNG free, or grab the full favicon kit ZIP (Pro) with all PNGs plus a site.webmanifest.
• Reference the files in your HTML head with <link rel="icon"> tags.

Limits: 5 free generations per visitor per day; individual PNGs are always free. The full kit ZIP is a Pro feature - IconVault Pro starts at $19/year, with unlimited runs of every tool.

The PNG to ICO Converter builds a real, standards-compliant Windows .ico file from your PNG - header, per-size directory entries and PNG-compressed image data - so it works as favicon.ico and as a Windows shortcut or taskbar icon.

How to convert

• Drop a square PNG (simple design, transparent background works best).
• Choose which sizes to include - 16, 32 and 48 are selected by default.
• Click “Download .ico”. The file is built locally and downloads instantly.
• Place it at your site root as /favicon.ico, or use it as a Windows app icon.

Limits: 5 free conversions per visitor per day, no account needed. IconVault Pro (from $19/year) unlocks unlimited conversions and unlimited runs of every tool. Files never leave your device.

The QR Code Generator turns URLs, text, Wi-Fi credentials and contact snippets into scannable QR codes. Export crisp black-on-white PNGs at 256, 512 or 1024px - sharp enough for cards, posters and packaging.

How to generate

• Type or paste your content - a URL, plain text, or Wi-Fi in the form WIFI:T:WPA;S:Name;P:Password;;
• Pick an export size: 1024px for print, 512px for screens.
• Style it: set error-correction (L/M/Q/H), QR and background colors, quiet-zone margin, or upload a center logo (auto-switches to H correction).
• Click “Generate QR code”, scan it with your phone to verify, then download the PNG.

Limits: 5 free generations per visitor per day. IconVault Pro (from $19/year) unlocks unlimited QR codes plus unlimited runs of every tool. Everything is generated on your device.

The Gradient Generator is a visual builder for CSS gradients. Set the angle, stack unlimited color stops with per-stop position sliders, toggle linear or radial, and copy clean CSS while a live preview updates in real time.

How to build a gradient

• Start from one of 12 curated presets (Sunset, Ocean, Neon…) or choose linear/radial and build from scratch.
• For linear, drag the angle slider (0–360°).
• Add color stops, pick each color, and drag position sliders to shape the blend.
• Click “Copy CSS” and paste the linear-gradient() or radial-gradient() declaration into your stylesheet.

Limits: 5 free CSS copies per visitor per day. IconVault Pro (from $19/year) unlocks unlimited copies and unlimited runs of every tool. No account needed to experiment.

The Color Converter translates any color between HEX, RGB, HSL, HSV, HWB, CMYK, CIE-LAB and LCH in real time - plus 100+ named colors. Type a value in any field, use the visual picker, or search a name, and every other format updates instantly.

Workflow

• 1. Pick a color, type a HEX/RGB/HSL/HSV/CMYK/HWB value, or search a named color.
• 2. All fields sync both ways - edit RGB and every format updates live.
• 3. Explore harmonies (complementary, triadic, tetradic…) and shades/tints - tap any swatch to use it.
• 4. Check WCAG contrast against black/white, then hit Copy on any format or export CSS variables.

5 free copies per visitor per day. Pro (from $19/year) unlocks unlimited conversions across all tools. Everything runs in your browser - nothing is uploaded.

The Contrast Checker computes the WCAG 2.1 contrast ratio between a text color and a background color, renders a live preview of your exact pairing, and scores it against all four bars: AA normal, AA large, AAA normal and AAA large.

Workflow

• 1. Enter or pick the text (foreground) color and the background color.
• 2. Press Check contrast - the ratio (e.g. 4.52:1) appears instantly.
• 3. Read the pass/fail pills: green means the pairing meets that WCAG bar.
• 4. Adjust the darker or lighter color until AA normal (≥ 4.5:1) passes - or hit Suggest AA fix to auto-nudge the text color to the nearest passing shade.
• 5. Use Swap colors to flip foreground and background in one click.

5 free checks per visitor per day. Pro (from $19/year) unlocks unlimited checks. The math runs entirely in your browser - nothing is uploaded.

The Box Shadow Generator designs CSS box-shadows visually: sliders for X/Y offset, blur and spread, a color picker with opacity control, and an inset toggle - with a live preview on a real card and one-click CSS copy.

Workflow

• 1. Start from a preset (Soft card, Floating, Glow, Neumorphic…) or drag the offset, blur and spread sliders while watching the live preview.
• 2. Pick a shadow color and set opacity - soft realistic shadows use black at 10–35% opacity.
• 3. Tick Inset for pressed-button or inner-glow effects.
• 4. Copy the generated box-shadow declaration into your stylesheet.

5 free copies per visitor per day. Pro (from $19/year) unlocks unlimited copies across all tools. Everything runs in your browser - nothing is uploaded.

The JSON Formatter pretty-prints messy JSON with 2-space indentation, minifies it for production, and validates it with plain-English error messages. Upload .json files straight from your computer.

Workflow

• 1. Paste JSON or upload a .json file (or try Load sample).
• 2. Press Format (2-space) for readable output, Minify for the smallest valid string, or Validate for a quick pass/fail. Tick Sort keys to alphabetize object keys recursively.
• 3. Invalid JSON shows the exact parse error and its position - usually a trailing comma, single quotes or unquoted keys.
• 4. Copy the output or download it as formatted.json.

5 free format/minify runs per visitor; validation is unlimited. Pro (from $19/year) unlocks unlimited runs across all tools.

Encode any text to Base64 and decode Base64 back to text - fully Unicode-safe, so emoji and non-Latin scripts round-trip correctly. The File tab converts any file into a Base64 data URL for inlining images, fonts and assets into HTML, CSS or JSON.

Workflow

• 1. Text tab: paste text and press Encode, or paste Base64 and press Decode. The tool auto-detects the direction on paste, and a Standard / URL-safe toggle handles base64url (as used in JWTs).
• 2. File tab: choose a file to get a data URL like data:image/png;base64,....
• 3. Copy the result - the character count is shown so you can judge payload size.
• 4. Paste data URLs straight into <img src>, CSS backgrounds or JSON payloads.

5 free conversions per visitor. Pro (from $19/year) unlocks unlimited conversions across all tools. Encoding runs locally in your browser - nothing is uploaded.

The JWT Decoder turns a compact auth token into readable JSON - header, payload, expiry and raw signature - entirely in your browser. Nothing you paste ever leaves your machine.

How to use it

• Copy the full token (header.payload.signature) from your app, DevTools or API response.
• Paste it into the decoder and hit Decode token.
• Optional: enter the HMAC secret to verify the signature (HS256/HS384/HS512) - the secret never leaves your browser.
• Read the header (algorithm, type) and payload (claims) as formatted JSON - copy either with one click.
• Check the expiry badge: green means valid, red shows how long ago it expired.
• Remember: this tool only decodes - it never verifies the signature. Verify tokens on your server.

Free plan: 5 decodes per tool. IconVault Pro (from $19/year) unlocks unlimited decodes and every other developer tool.

The Regex Tester is a live workbench for JavaScript regular expressions: type a pattern, toggle flags, paste a test string, and see matches highlighted with capture groups listed - all in your browser.

How to use it

• Type your pattern in the pattern field (no slashes needed).
• Toggle flags: g (global), i (ignore case), m (multiline), s (dotall), u (unicode), y (sticky).
• Paste a test string and hit Test - matches are highlighted inline, with index and groups under Match details.
• If the pattern is invalid, the red error shows the engine's exact complaint - fix it and re-test.
• Use Copy /pattern/flags to drop the literal straight into your JavaScript.
• Try the Replace panel: enter a replacement with $1-style backreferences and preview the result before touching your code.

Free plan: 5 tests per tool. IconVault Pro (from $19/year) unlocks unlimited tests and every other developer tool.

The Timestamp Converter translates Unix epoch values into human-readable dates - and back. It handles both seconds and milliseconds, shows UTC, local time and relative time, and runs fully client-side.

How to use it

• Epoch → date: paste the number - seconds, milliseconds, microseconds and nanoseconds are auto-detected by digit length (a “detected: …” label confirms it). You get UTC ISO, local time and a relative phrase.
• The duration calculator converts seconds to and from 1d 2h 3m 4s notation, both ways, live - handy for TTL and cache debugging.
• Date → epoch: pick a date/time and hit Convert to epoch - you get both epoch seconds (most APIs) and milliseconds (JavaScript).
• Use the Now button to fill the current time instantly.
• Click any UTC or Local result to copy it.

The URL Encoder / Decoder handles percent-encoding the way browsers do: encodeURIComponent for single query values, encodeURI for full URLs, and a smart decode mode - all in your browser.

How to use it

• Pick a mode: encodeURIComponent (query param) encodes everything unsafe; encodeURI (full URL) keeps : / ? & = # intact; Decode reverses %XX sequences.
• Paste your text and hit Encode/Decode - the output appears with a Copy button.
• Use “Use as input” to move the output back and round-trip the conversion.
• The char counter shows how much the string grew - useful for spotting double-encoding.

The UUID Generator creates cryptographically secure version 4 UUIDs with the browser's built-in crypto.randomUUID() - 1, 10, 50 or 100 at a time, with per-item and batch copy. Nothing is sent anywhere.

How to use it

• Choose how many UUIDs you need: 1, 10, 50 or 100 - in v4 or time-ordered v7 (RFC 9562, the modern default for database keys), with uppercase and no-dashes format options.
• Hit Generate - the batch appears instantly.
• Click the copy icon next to any UUID, or Copy all for the whole batch as newline-separated text.
• Paste straight into database seeds, API keys, config files or test fixtures.

The Password Generator creates cryptographically secure random passwords with your browser's built-in random number generator. Nothing is sent to a server or stored - the password exists only in your tab.

How to use it

• Drag the length slider (8–64 characters) - 16+ is recommended for important accounts.
• Toggle lowercase, uppercase, digits and symbols to shape the character set - or exclude ambiguous characters (l, 1, I, 0, O).
• Switch to the Passphrase tab for memorable multi-word passwords: 3–12 words, your choice of separator, optional capitalization and a trailing number.
• Hit Generate password and watch the live entropy meter - aim for 80+ bits (Strong).
• Copy the result into your password manager.

How to use it

• Paste the original text into the left box and the modified text into the right box.
• Hit Compare - the diff renders below with line numbers, and changed characters inside modified lines are highlighted inline.
• Red lines with − exist only in the original; green lines with + exist only in the modified text.
• Dim lines are unchanged and shown for context.

The Hash Generator computes MD5, SHA-1, SHA-256, SHA-384 and SHA-512 digests of any text, all at once. SHA hashes use your browser's WebCrypto; MD5 uses a standards-compliant inline implementation.

How to use it

• Paste or type any text into the input box.
• Hit Generate hashes - all five digests appear instantly.
• Use the copy button on any row to copy that hash.
• SHA-256 is the safe default for checksums and integrity checks.
• HMAC mode signs text with your secret key (HMAC-SHA-256/512) - handy for debugging webhook signatures. Paste an expected hash to get a green Match / red Mismatch verdict.
