App Icon Generator

Every platform asks for its icon at different pixel sizes. iOS uses point sizes multiplied by the screen scale: a 60-point home-screen icon is 120 px on a 2× iPhone and 180 px on a 3× iPhone, and iPad and the App Store add 76, 83.5 and 1024-point variants. This generator renders all 13 unique iOS pixel sizes, from 20 to 1024 px. It writes them into an AppIcon.appiconset folder with a Contents.json that maps each file to its idiom, size and scale, so Xcode recognises the set immediately.

Apple applies its own rounded-corner mask and rejects icons with transparency. That's why the iOS images are always exported as fully opaque squares: any transparent area gets your chosen background colour (white by default), and the corner radius setting is ignored for iOS. Android and PWA icons respect your transparency and corner radius, so you can export rounded or circular launcher icons.

For Android, the ZIP mirrors the res folder layout: ic_launcher.png in mipmap-mdpi (48 px), hdpi (72 px), xhdpi (96 px), xxhdpi (144 px) and xxxhdpi (192 px), plus a 512 × 512 icon for the Google Play listing. For Progressive Web Apps it adds 192 and 512 px icons and a 512 px maskable icon. The maskable icon is opaque, square and padded, so the artwork stays inside the safe zone when Android crops it into a circle or squircle.

Your image is drawn into each size on a canvas with high-quality resampling, entirely in the browser, and nothing is uploaded. Use a square source of at least 1024 × 1024 px for the sharpest results. Non-square images are fitted inside the square, and the tool warns you when that happens. Padding gives artwork breathing room, which matters for logos that touch the edges.
