App Icon Generator
One image to every iOS, Android and web size.
Drop a square image, or click to choose
1024×1024 PNG works best. Nothing is uploaded — resizing happens in this tab.
Add an image to get started.
iOS applies its own rounded-corner mask and rejects icons with transparency — for the App Store 1024pt icon, use a solid background and leave the corner radius at 0.
About this tool
Upload a single square image and download a complete set of iOS, Android, favicon and PWA icons — resized in your browser, never uploaded.
It runs completely in your browser — no input is sent anywhere, so it is safe to use with data you would not paste into a hosted service.
