App Icon Generator Guide
What is App Icon Generator?
App Icon Generator is an app icon resizer for mobile developers who need release-ready assets for Xcode and Android Studio. Upload one square icon design and generate the formats required for iOS, Android, favicon, and PWA projects. For best results, start with a 1536x1536 source image so smaller launcher, notification, and favicon sizes stay sharp after downscaling.

Common questions
What source image size should I use?
Use a square 1536x1536 PNG for the best results. The tool accepts square images down to 512x512, but smaller sources may make high-density app icons look less sharp.
Is this optimized for Xcode and Android Studio?
Yes. Apple output includes an AppIcon.appiconset with Contents.json for Xcode, and Android output includes mipmap folders plus adaptive icon XML for Android Studio projects.
Does this generate Android adaptive icons?
Yes. The Android output includes density folders, foreground images, background XML, and adaptive icon XML when the adaptive icon option is enabled.
Are my uploaded app icons sent to a server?
No. App icon generation runs in the browser for supported workflows, so your source image stays on your device.
