App Icon Generator

At least 1024×1024, square, and ideally exported from a vector original so edges stay crisp at every size. Everything is generated down from that master — starting smaller means the large iOS App Store icon has to be upscaled, which looks soft exactly where it is most scrutinised.

Because iOS and Android organise assets differently. iOS expects a set of named sizes in an asset catalogue, while Android uses density buckets like mdpi through xxxhdpi. Sorting them into the right folder structure means you can drop them straight into Xcode or Android Studio without renaming anything.

For iOS, no — Apple requires a fully opaque square and applies its own rounded mask, so transparent corners appear black. Android is more flexible and adaptive icons genuinely use transparency. When in doubt, supply an opaque square and let each platform mask it.

Yes, App Icon Generator is completely free. No signup, no account, and no watermark on outputs. A Pro tier is available for 100 AI ops/day and larger file sizes.

App Icon Generator uploads your file over an encrypted connection to our own processing server, converts it, and returns the result. The file is deleted immediately after processing and is never used for anything else. It is not sent to any third party, and we keep no copies.
