App Icon Generator - Generate iOS & Android Icons

A 20pt to 1024pt including @2x and @3x variants.

A 48dp (mdpi) to 512dp (Play Store).

A PNG, square, no transparency.

A For optimal quality across all generated app icon sizes, your original source image should be at least 1024x1024 pixels. A larger resolution, like 2048x2048 or even 4096x4096, is even better for future-proofing and ensuring crispness on high-density displays. The App Icon Generator will then accurately scale this high-resolution input down to all necessary iOS and Android dimensions.

A For optimal results, your source image should be square and opaque. If you upload a non-square image, the generator will typically center it and pad the shorter dimension to make it square, potentially adding whitespace or black space. Transparent areas will generally be rendered as black or white backgrounds, or might cause unexpected visual artifacts across various icon sizes. We recommend ensuring your initial image is a solid, square canvas.

A No, you don't need any specialized design software like Photoshop or Sketch. This tool is designed for simplicity. You upload a single image, and the generator handles all the complex resizing and formatting for both iOS and Android platforms automatically. It's ready for use right after you download the ZIP file.

A Yes, you can use any image you own the rights to. But app icons look best with simple, bold shapes and minimal detail. A photo of your cat might get muddy when scaled down to 20pt. Test it: upload a 1024x1024 image and check how the 29pt version looks. If details blur or text becomes unreadable, simplify your design.

A Each icon gets the exact Apple-required filename, like icon-20@2x.png or icon-1024.png. The tool groups everything into an Assets.xcassets-ready folder structure inside your ZIP. Drag that folder straight into Xcode — no renaming needed. Android files follow the same logic with mipmap prefixes. One upload, both platforms handled correctly.

A No hard cap exists — I've tested images up to 8000x8000 px without issues. But anything above 4096x4096 is overkill for app icons. Huge files just slow down the generation and inflate your download. Stick with 1024x1024 or 2048x2048 for the best balance of crisp output and fast processing.

A No, this generator doesn't produce dark or tinted icon variants automatically. iOS 13+ supports dark mode app icons, but Apple's system treats those as optional replacements you configure manually in Xcode. Your ZIP contains the standard light-mode set for both platforms — 44 files total for iOS, 8 for Android. If you need dark mode icons, upload two source images separately and rename the dark set yourself. I'd suggest naming them icon-dark-29@2x.png to keep things organized.
