App Icon Generator topic guide
Generate icons for an iOS app
Direct answer
Produce the full ladder of iOS, iPadOS and App Store icon sizes from one uploaded image, organised for Xcode.
What this workflow handles
Modern Xcode asset catalogs expect 13 icon sizes from 20 by 20 up to 1024 by 1024 pixels. The package ships the exact filenames an AppIcon.appiconset expects, so a copy-and-paste workflow into Xcode is enough for most projects.
Use the app icon generator to download every supported size and format in one ZIP, then pick the files your platform or framework actually requires.
How to use it
- Upload your source image
- Generate the iOS icon ladder
- Drag the icons into Xcode AppIcon.appiconset
Frequently asked questions
Which iOS icon sizes do I need?
Modern Xcode asset catalogs expect 13 sizes in total: 20 by 20, 29 by 29, 40 by 40, 58 by 58, 60 by 60, 76 by 76, 80 by 80, 87 by 87, 120 by 120, 152 by 152, 167 by 167, 180 by 180 and 1024 by 1024 pixels. The 1024 by 1024 PNG is used by the App Store; the smaller sizes cover iPhone, iPad, settings and notifications.
Does iOS flatten transparent icons?
No, iOS does not flatten app icons. The icon is drawn on top of the system wallpaper, so transparent pixels show through. iOS does apply a rounded mask automatically; you do not need to round the corners yourself. Keep the source square and let the OS handle the masking.
