App Icon Generator

One image, every app icon you need

Shipping an app means producing dozens of icon files at specific sizes, with the right names, folders and manifests. This tool does that from a single image and hands you one zip.

Steps

1. Drop your artwork onto the page. Start from a square 1024 x 1024 image or larger.
2. Choose how it fits: Whole image keeps all of it, Fill crops to the square.
3. Set padding if the artwork touches the edges, and pick a background colour for transparent areas.
4. Tick the platforms you need: iOS, Android and PWA.
5. For PWA, add your app name and theme colour.
6. Check the previews, then download the zip.

What you get

iOS: an AppIcon.appiconset folder with every iPhone and iPad size, from 40 to 180 pixels, plus the 1024 pixel App Store icon, and a Contents.json that lists them. Drag the folder into your asset catalog in Xcode. A single-size version of Contents.json is also included for Xcode 14 and newer.

Android: mipmap folders for mdpi to xxxhdpi containing the classic square icon, the round icon and an adaptive foreground layer, plus the adaptive icon XML files, the background colour resource and a 512 pixel Google Play icon. Copy the res folder into your project.

PWA: icons from 72 to 512 pixels, two maskable icons whose artwork sits safely inside the mask, a manifest snippet and the head tags to link everything together.

Design tips

• Keep one simple, bold shape. Detail disappears at 40 pixels.
• Avoid text except for a single letter or logo mark.
• Leave breathing room around the artwork. Adaptive and maskable icons can be cropped to a circle.
• Do not round the corners yourself. iOS applies its own mask.
• Test on a real home screen before release.
