About this tool
This app icon generator runs entirely in your browser: your logo is drawn to a local canvas at every required size and packaged with fflate — no upload, no account, no watermark. Transparent PNGs stay transparent unless you pick a background colour, and maskable icons automatically get extra padding for Android's safe zone.
The ZIP mirrors the folder layout most projects expect (ios/, android/, favicon/ and pwa/) and includes a starter manifest.json plus the matching HTML link tags. Replace the placeholder app name and icon paths before shipping.
