PWA Icon Sizes & Presets
Progressive Web Apps require specific icon sizes in the web app manifest to enable installation on mobile and desktop. The two essential sizes are 192x192 and 512x512 PNG. A maskable icon variant ensures your app icon looks correct on Android devices that apply different shaped masks. FastEdit generates all required PWA icon sizes from a single source image.
Pick this preset, drop your file, and FastEdit starts from the PWA (Progressive Web App) Icon 192 dimensions, format, and file-size target.

- Both 192x192 and 512x512 icons are required in the manifest: Chrome will not show the install prompt without them.
- Maskable icons need all important content within the center 80% (the "safe zone"): the outer 20% may be cropped by the device.
- Test maskable icons with the Maskable.app tool to preview how they look with different shaped masks.
- Use the "purpose" field in your manifest to specify "any" for standard icons and "maskable" for padded variants.
- Include both a standard and maskable version of your 512x512 icon for the best cross-device experience.
