About this tool
Turn one reviewed raster image into structured Xcode and Android launcher-icon resources without uploading the artwork.
App Icon Resizer is useful when one source image needs to become the common Android and iOS icon sizes quickly. It helps product teams prepare delivery-ready icon exports without manually resizing each dimension in design software.
- Creates 15 default iOS and iPadOS PNG assets with an AppIcon.appiconset Contents.json file.
- Creates Android legacy, round, and 108dp adaptive foreground mipmaps across five densities plus adaptive XML and a Play listing icon.
- Supports full-art fitting or explicit center cropping, a flat background, and a 48–66dp Android safe-artwork control.
- Verifies every generated PNG signature and dimensions before producing a project ZIP with a manifest and integration notes.
How to use App Icon Resizer
Upload a square source image, review the generated sizes, and download the icon set once the smallest versions still look clear. If the artwork has fine detail, inspect the reduced outputs first so the icon remains readable at launcher and settings sizes.

Examples you can test
Load an example, compare the result with the expected output, then replace it with your own input.
Prepare an iOS app icon set
Example input
Source: 1024x1024 PNG
Expected output
Multiple square icon sizes for app store and device contexts
Start from the largest required source so smaller outputs remain sharp.
Check safe area padding
Example input
Source logo touches image edges
Expected output
Small sizes look cramped
Add padding around the mark before resizing if the icon loses clarity at small sizes.
Validation checklist
- Use a square, high-resolution source image.
- Inspect the smallest output sizes for legibility.
- Confirm platform-specific icon requirements before uploading.
