App Icon Generator
Drop one square image and download a ZIP with every icon size Xcode and Android Studio expect. The resizing happens in your browser; your image is never uploaded.
What's in the ZIP
ios/AppIcon.appiconset/: 18 PNGs for iPhone, iPad and the App Store, withContents.json. Replace the folder of the same name inAssets.xcassets.macos/AppIcon.appiconset/: the 10 Mac sizes withContents.json.android/res/mipmap-*/ic_launcher.png: five densities, plus a 512 pxplaystore-icon.png.
Every size is listed in the app icon sizes guide.
Frequently asked questions
Is my image uploaded?
No. The image is resized with your browser's canvas and the ZIP is built on your device.
What size should my source image be?
A square 1024×1024 PNG. Smaller images work but the large sizes get blurry; non-square images are cropped to the centre.
Why fill transparent areas?
App Store icons for iPhone and iPad must not be transparent, so transparent pixels are filled with the colour you choose. Mac and Android icons keep their transparency.
