App Icon Generator & Store Screenshot Resizer
Drop in one source image and get every icon size iOS and Android ask for — including a valid Contents.json and adaptive icon config — or resize screenshots to every App Store Connect and Play Console slot.
Everything runs in your browser using canvas. No signup, no watermark, and your images are never uploaded anywhere.
What you get
A drag-and-drop iOS asset catalog. The zip contains a complete AppIcon.appiconset with its Contents.json, so it drops straight into Xcode. Most generators skip the manifest, which is why their output shows up as empty slots.
Android adaptive icons done properly. Android 8+ masks icons to an OEM-chosen shape, and only the centre 66dp of the 108dp canvas is guaranteed visible. The foreground layer is inset to that safe zone, so your icon survives circular, squircle, and teardrop masks without clipping — plus round icons and the 512px Play Store listing icon.
Screenshots in upload-slot folders. Output is organised as ios/6.9-inch/, android/phone/ and so on, so each folder maps to one slot in App Store Connect or the Play Console. Fit mode letterboxes with a background colour you pick; fill mode centre-crops.
