Free app icon generator

Upload a square 1024×1024px PNG (or larger). That is the App Store master size, and every smaller iOS and Android icon is downscaled from it for the sharpest result. Smaller sources still work but can look soft.

No. The generator runs entirely in your browser using the HTML canvas. Your image never leaves your device, and nothing is stored or sent anywhere.

For iOS it exports the full Xcode AppIcon set (1024, 180, 167, 152, 120, 87, 80, 76, 60, 58, 40, 29 and 20px). For Android it exports the five launcher density buckets (mdpi 48px through xxxhdpi 192px) plus the 512×512 Google Play Store icon.

No - Apple requires the 1024px App Store icon to be fully opaque with no alpha channel. If your icon has transparent areas, enable 'Flatten transparency' and pick a background color before exporting.

The zip is organized into ios/AppIcon.appiconset and android/mipmap-* folders. Drag the iOS files into your Xcode asset catalog, and drop the Android mipmap folders into your res/ directory. Use the 512px PNG for your Google Play listing.

This tool generates every required export size from your existing icon - it does not design new artwork. If you already have an app icon and need it in every iOS and Android size instantly, this is the fastest way to do it. If you need help designing the icon itself first, use any image editor to create your 1024x1024px source, then bring it here for sizing.
