IconVault's URL Encoder / Decoder handles percent-encoding the way browsers do. Choose encodeURIComponent for a single query parameter or form value (encodes everything unsafe), encodeURI for a full URL (keeps : / ? & = # intact), or Decode to turn %XX sequences back into readable characters - with a smart fallback that handles full-URL encodings too.

Everything runs in your browser: nothing is uploaded, logged or stored, so it's safe for URLs containing tokens or PII. Input/output character counts show exactly how much the string grew, and one click moves the output back into the input for round-trip checks. Every visitor gets 5 free encodes - IconVault Pro ($12/year) unlocks unlimited use of every developer tool.
