App Icon Design Guidelines for iOS and Android

Your app icon is the first impression users have of your app. Both Apple and Google have strict technical requirements for the icons you upload to their developer consoles.

Apple App Store Icon

When uploading an icon to App Store Connect, it must meet these exact specifications:

• Dimensions: 1024 × 1024 pixels
• Format: PNG (flattened, no transparency)
• Color Space: sRGB or P3
• Shape: Square (do not round the corners; Apple automatically applies their standard squircle mask).

Google Play Store Icon

Google Play requires a separate high-resolution icon for the store listing:

• Dimensions: 512 × 512 pixels
• Format: 32-bit PNG (with alpha/transparency)
• Max Size: 1024 KB
• Design: Follow Google's Material Design guidelines. Do not include drop shadows (Google adds them).

Key Differences

The biggest mistake developers make is trying to use the same asset for both stores. Apple requires a 1024x1024 square with NO transparency. Google requires a 512x512 PNG that CAN include transparency (though they strongly recommend full-bleed icons that use their automatic masking).
