Transform a single master image into complete iOS Xcode Asset Catalogs, Android Play Store adaptive densities, and Web PWA favicons. Download as a pre-structured ZIP bundle.
Runs entirely in your browser
Shipping an app means producing its icon in dozens of sizes and formats — iOS asset catalogues, Android adaptive densities, and web PWA favicons — which is tedious to do by hand. This generator takes one master image and outputs the complete set, packaged as a structured ZIP you can drop into your project.
It produces the right structures for each platform: an Xcode Asset Catalog with the correct Contents.json for iOS, adaptive-density PNGs for Android and the Play Store, and favicon sizes for a Progressive Web App. That means the output is not just resized images but the exact layout each toolchain expects, so integration is a matter of copying files in.
The whole process runs in your browser, so your master image is not uploaded. Start from a high-resolution square image (a squircle mask is applied where platforms expect it) to get clean icons at every size in a single download.
