What is an app icon generator?

An app icon generator is a free developer tool that converts a single master artwork into all required icon dimensions and folder structures for iOS, Android, Flutter, React Native, PWA, and Web platforms.

What image formats and dimensions should I upload?

For optimal quality across all display densities, upload a square 1024 × 1024 pixel PNG, JPG, WebP, or SVG file with high resolution.

How do I make an app icon for iOS and Apple App Store?

Upload your image, choose iOS or All Platforms, customize padding and background color, and download the Xcode-compatible Assets.xcassets archive.

How do I generate Android adaptive and mipmap icons?

Upload your artwork, select Android, adjust the safe-zone padding to fit adaptive circular masks, and download the organized res/ mipmap density suite (mdpi to xxxhdpi).

Can I use this tool for Flutter and React Native apps?

Yes! Flutter and React Native apps rely on standard native iOS xcassets and Android res/mipmap directories, which are generated in the downloaded ZIP archive.

Is the app icon generator completely free and private?

Yes, our App Icon Generator is 100% free with unlimited usage. All image rendering and compression takes place locally inside your browser using HTML5 Canvas — zero files are uploaded to any server.
