About this tool
IconVault's PWA Manifest tool builds a complete web app manifest.json for your progressive web app. Fill in the app name and short name, theme and background colors, display mode, start URL, scope and orientation, then upload one icon and let the tool generate real 192px and 512px PNGs from it right in the page.
Add app shortcuts, preview the live JSON as you edit, then copy or download the manifest plus the icon files. Everything runs fully in your browser with nothing uploaded, so your branding never leaves your device. It is free to try (repeated use may ask for Pro).
