How to use

3Download the ZIPChoose the platforms you need, download the ZIP and drop the folders into your project.

When it helps

Each platform requires different icon sizes, so releasing an app means making dozens of separate images. From one original, this tool creates every size needed for iOS, Android, the Play Store and the web, with the folder structure already in place.

The iOS output matches Xcode's AppIcon.appiconset folder, so it is recognized as soon as you put it inside Assets.xcassets. The Android output includes regular and round icons for mipmap-mdpi through xxxhdpi, plus the adaptive icon foreground image and XML used on Android 8 and later.

Adaptive icons are cropped into different shapes, such as circles or rounded squares, depending on the device. The foreground image is therefore scaled down automatically to fit inside the central safe area. Always check the preview to make sure your logo is not cut off.

FAQ

What size should the original be?

A 1024×1024 square PNG is best. Smaller images work, but large icons may look blurry.

Should I round the corners before uploading?

No. iOS and Android apply the shape themselves. Upload a square original so no empty gaps appear in the corners.

Can iOS icons be transparent?

The App Store rejects transparent icons, so iOS icons are filled with the background color.

What about the Android adaptive icon background?

The background color is written to values/ic_launcher_background.xml. To use a background image, change the background in the XML to an image.

I also need a website favicon.
