App icon generator
Turn one image into complete iOS and Android icon sets, ready to drop into a project.
DeveloperRuns on your device. Nothing is uploaded.
How it works
Add an image
Use 1024×1024 or larger. You'll get a warning if it's smaller.
Set the background
iOS icons can't be transparent, so choose a colour.
Check the shapes
The previews show how each platform's mask crops it.
Choose sizes
Turn on legacy iOS sizes only if your project needs them.
Download
Copy the folders into your Xcode and Android projects.
Questions
Xcode 15 and later generate all sizes from a single 1024 px icon. Turn on legacy sizes for older projects.
Android keeps the logo and background as separate layers, and each device masks them into its own shape. The logo stays inside the middle 66 dp of the 108 dp layer, which no mask clips.
Not on iOS, where the App Store rejects it. So every iOS icon here gets the background colour you set.
No. Building your icons happens in your browser, so nothing is sent to a server.
