App Icon Generator
Drop in a 1024×1024 image and get every Android and iOS icon size instantly — Xcode-ready and Android Studio-ready ZIPs included.
What is an App Icon Generator?
Mobile apps require icons in many specific sizes for different contexts: home screen, App Store listing, Settings, and Spotlight search. iOS requires sizes from 20x20 to 1024x1024 pixels, and Android requires multiple densities from mdpi (48x48) to xxxhdpi (192x192). Generating all these sizes manually from a master image is tedious and error-prone.
This tool generates all required iOS and Android app icon sizes from a single 1024x1024 image and packages them in Xcode-ready and Android Studio-ready ZIPs.
How to generate app icons online
- Upload a 1024x1024 PNG image (square, no rounded corners — iOS adds them automatically).
- Choose iOS, Android, or both.
- Download the ZIP and drop the folder into your Xcode or Android Studio project.
Frequently Asked Questions
What resolution should my master app icon be?
Use 1024x1024 pixels. This is the maximum size required by the Apple App Store and provides enough resolution to scale down to all smaller sizes without quality loss.
Should my app icon have rounded corners?
For iOS, do not add rounded corners to your source image — iOS applies them automatically to the correct radius for each device. For Android, the system applies the adaptive icon shape based on the device theme.
What are Android adaptive icons?
Android 8 and above supports adaptive icons, which have separate foreground and background layers. The launcher applies a shape (circle, rounded square, squircle) based on the device theme. This tool generates the traditional mipmap icons used in older Android versions.
Does this tool process my image on a server?
No. All image resizing runs in your browser using the Canvas API. Your icon image never leaves your device.
