App icon sizes: iOS and Android (complete list)
2026-07-21
You upload a single high-resolution icon to the store; the system generates the smaller sizes.
| Store | Size | Format / rule |
|---|---|---|
| App Store | 1024 × 1024 | NO alpha (24-bit); don't round the corners — Apple rounds automatically |
| Google Play | 512 × 512 | 32-bit PNG (alpha allowed); Play applies the mask itself |
Common mistakes
- Transparency in the App Store icon → rejected. Fill the background.
- Pre-rounding the corners → double-rounding shows. Submit a square.
- Putting "download", a price, or an award badge inside the icon is not allowed.
When you select the icon target, Vitrinshot outputs the 1024 and 512 files at the correct size and format.
