Submitting apps to the Apple App Store and Google Play requires exporting dozens of exact pixel dimensions, from tiny 20px notification icons up to master 1024px store artwork. ImageUp takes your single master artwork and automatically generates production-ready Xcode Asset Catalogs (`AppIcon.appiconset/Contents.json`) and Android `res/mipmap` directory hierarchies in one click.
Drop your square master artwork (PNG format with flat edges, no pre-rounded corners).
Choose iOS (iPhone, iPad, Watch), Android (Adaptive mipmap sizes), or Both.
Unzip and drag the generated folders directly into Xcode or Android Studio.
Generates the complete `AppIcon.appiconset` folder with formatted `Contents.json` ready for direct drag-and-drop into Xcode.
Includes all standard DPI densities: `mipmap-mdpi` (48px), `hdpi` (72px), `xhdpi` (96px), `xxhdpi` (144px), `xxxhdpi` (192px), plus 512px Play Store asset.
Inspect realistic simulated previews on an iOS dark springboard and an Android circular adaptive icon launcher.
No. Upload a perfectly square image. Apple's iOS springboard and App Store rendering engine automatically apply the continuous squircle curve and border masks.
No. Apple strictly requires opaque background pixels for App Store master icons. Any transparent regions will be filled with black on iOS.
Open your Xcode project, navigate to `Assets.xcassets`, delete the existing empty `AppIcon`, and drag the extracted `AppIcon.appiconset` folder directly into the asset catalog navigator.
Copy the generated `mipmap-mdpi`, `mipmap-hdpi`, `mipmap-xhdpi`, `mipmap-xxhdpi`, and `mipmap-xxxhdpi` folders into your Android project's `app/src/main/res/` directory.
Creating app icons for iOS and Android doesn't have to be a headache. Whether you are launching a new project on the App Store or pushing an update to Google Play, getting the exact pixel dimensions right is normally a tedious task. You have to juggle tiny 20px notification icons, standard home screen sizes, and the large 1024px master artwork required for storefronts.
Instead of manually resizing images and trying to remember which folder structure Xcode or Android Studio expects, you can just drop your square 1024x1024 master image right here. Our generator automatically scales your artwork into every single required dimension. It handles the continuous squircle masks for Apple's iOS springboard and formats the circular adaptive icons for modern Android devices. Everything is organized into ready-to-use developer folders, including the exact Asset Catalog configuration files you need.
You also get a live preview to see exactly how your app will look on a user's home screen before you download anything. Since the entire resizing process happens directly inside your browser, your unreleased app designs stay entirely private on your device. Just upload, preview, and download your complete icon package in seconds.
