Which platforms and icon sizes are supported?

The generator covers iOS, Android, Web (favicon and PWA manifest), macOS, Windows, watchOS, tvOS, visionOS, HarmonyOS, uni-app, and Quasar, producing every required size for each platform automatically.

How do I get the correct iOS app icon corner radius?

iOS applies its own rounded mask at runtime, so you should supply a full square icon and let the system round the corners. Use the border radius control only for previews or platforms that expect pre-rounded icons.

What image formats can I upload?

You can upload PNG, JPG, or JPEG files. PNG is preferred when your icon has transparency, since the tool preserves the alpha channel during resizing.

Is this app icon generator free to use?

Yes. The tool is completely free with no sign-up or upload required—generate and download as many full icon sets as you need directly in the browser.
