アプリアイコンパックジェネレーター

One app icon, every size Android and iOS ask for

Shipping an app means exporting the same app icon over and over at different sizes. This generator does it in one step: upload a single square image and you get Android launcher icons in all five mipmap densities, the Play Store icon, and a complete iOS AppIcon set with its Contents.json.

The files are named and foldered the way Android Studio and Xcode expect, so there's no renaming or guessing which size goes where.

What's in the ZIP

Designing an app icon that works at every size

• Start at 1024 × 1024. Everything is scaled down from your upload, so a large source keeps the small sizes sharp.
• Leave a margin. Android launchers often show icons in circles or rounded squares, and iOS rounds the corners. Keep important details inside the middle 80% of the image.
• Use a solid background. It's required for the App Store icon and looks more consistent on Android home screens.
• Skip text. Words become unreadable at 40 pixels. A single symbol or letter reads better.
• Check the smallest size. Open the 40 px file and see whether the icon is still recognizable.

Free and private

The app icon generator is free, has no sign-up, and runs on your device, so unreleased artwork stays confidential. Need a browser tab icon for your app's website too? The favicon generator makes one from the same file.
