iOSApp Icon Size Generator
Start with a 1024×1024 master icon and export common iOS sizes.
The sizing strategy that scales
Keep a single high-quality master icon (1024×1024). Export down to the sizes you need for your asset catalog.
Downscaling from a clean master icon reduces artifacts and keeps edges crisp.
Where sizes matter most
Small sizes (40–60px) are the hardest. Design for clarity there, not for the 1024px canvas.
Use strong contrast and simplify shapes to avoid blur and noise.
Practical checklist for developers
Verify the icon doesn’t rely on transparency tricks. Keep it readable on both light and dark backgrounds.
Drop the icon set into Assets.xcassets and commit it so teammates get identical results.
Common questions
What is the most important iOS icon size?
1024×1024 is the master icon for App Store Connect. Small previews are the best clarity test.
Do I need to export every size file?
Not always. Many teams keep only the master icon and rely on tooling, but explicit exports can be helpful.
Why do my icons look blurry?
Usually the crop is off, or the source isn’t clean. Start from a sharp master icon and scale down carefully.
Where do I put the icons in my project?
In Xcode: Assets.xcassets → AppIcon.
