App Icon Generator
A fast online app icon generator for iOS, Android, Windows, macOS, Linux, and the web. Upload one high-resolution image and get every size your app needs - no signup, no install.
Use this app icon generator to produce a complete icon set from a single source image. The tool outputs iPhone, iPad, App Store, Android mdpi–xxxhdpi, Play Store, Windows, macOS, Linux, and web-app sizes - all named correctly for each platform.
Start with a 1024 × 1024 PNG or JPG and download a ZIP that you can drop into Xcode, Android Studio, your desktop build, or a web manifest. Ideal for launch-day submissions and rapid icon updates during development.

If you only need a favicon or a PWA icon set, try the dedicated favicon generator or PWA icon generator.
Common pitfalls
Using a small source image
Upload a design at 1024 × 1024 px minimum. Smaller sources look blurry at the largest sizes.
Leaving transparent backgrounds
iOS expects a solid background. Transparent pixels can show the system chrome through the icon.
Including text in the icon
Text becomes unreadable at 48 px. Use a symbol or monogram that works at every size.
Not rounding corners yourself
iOS and most launchers mask icons automatically. Don’t pre-round - ship a full square design.

Frequently Asked Questions
Is the app icon generator free to use?
Yes. It’s free and runs in your browser - no signup, no install.
What source image size do I need?
Start with a square image at 1024 × 1024 px or larger. Smaller sources look blurry on high-resolution targets like App Store artwork or xxxhdpi.
Which platforms are included?
iOS (iPhone, iPad, App Store), Android (mdpi through xxxhdpi plus Play Store), Windows, macOS, Linux, and web-app icons.
Should I round the corners myself?
No. iOS and most launchers mask the icon automatically. Ship a full square design and let the platform apply its shape.
Can my icon have a transparent background?
For Android and web it’s fine. iOS expects a solid background - transparent pixels can look off, so use a coloured fill.
Does the tool upload my file to a server?
Generation runs in your browser. Files are processed locally and not stored on our servers.
