Ultimate App Icon Generator

Preparing app icons for app stores and different operating systems is notoriously tedious. Our App Icon Generator takes a single master image (ideally 1024×1024) and instantly generates over 40 precisely scaled icons for iOS, macOS, watchOS, and Android.

It doesn’t just resize your images—it packages them into developer-ready folder structures, complete with Xcode Contents.json files and Android mipmap directories, inside a single downloadable ZIP file.

Why Use This App Icon Generator?

• Developer-Ready ZIP Export — Stop manually renaming files. We automatically generate an AppIcon.appiconset folder for Xcode (with a pre-configured Contents.json) and res/mipmap-* folders for Android Studio. Just drag, drop, and code.
• All Platforms at Once — Instantly output the required icon dimensions for iPhone, iPad, watchOS, macOS, and Android simultaneously.
• Built-in Smart Cropper — Not a perfect square? No problem. Use our built-in UI to frame and crop your image to a flawless 1:1 aspect ratio right in your browser.
• 100% Private & Secure — Your app’s assets are your business. All image processing, cropping, and ZIP compression happen entirely locally in your browser. No images are ever uploaded to our servers.
