Frequently Asked Questions
What sizes does the app icon generator produce?
It generates all the sizes your app actually needs — iOS home screen, settings, notifications, and Spotlight — plus a 1024px master for the App Store.
Can I generate both iOS and Android icons?
Yes. The tool outputs iOS icon sets and Android mipmap sizes from the same source image, so you can ship both platforms without remaking anything.
Does it work with transparent icons?
Yes. Transparent PNG sources are handled correctly. Just note that Apple requires the final 1024px App Store icon to have no alpha channel — the tool lets you flatten that copy.
Is it free? Are my images private?
Yes. Free with no sign-up, and everything is generated locally in your browser — your images never leave your device.
