App Icon Generator - Generate iOS & Android Icons

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.

A Not automatically — it depends on your source art. A 1024x1024 image with thin lines or tiny text will turn into a blurry mess at 20pt regardless of resolution. Vector-based designs work best because they're clean at any size. I always tell people to zoom way out on their monitor until the image is thumb-sized. If you can still read text or see distinct shapes, you're golden. Test a 29pt render before committing to the full batch.

A Your image gets uploaded to our server for processing, then deleted from our storage within 60 minutes of the ZIP being generated. We don't train AI models on your uploads, and we never share them with third parties. The download link expires after 24 hours, so grab your ZIP right away. If privacy is a hard requirement, use a dummy image first to see if the output quality works for you before uploading your real logo.

A No, that's the whole point of generating multiple sizes. The ZIP includes @2x and @3x variants (like icon-60@3x.png) that match Apple's pixel density requirements exactly. For Android, you get mipmap folders for mdpi through xxxhdpi, covering 48px to 192px. Each file is rendered from your original at that exact scale, so no upscaling happens after the fact. Just make sure your source image is 1024x1024 or larger — anything less and the largest sizes will interpolate. Quick test: zoom your source to 20% in any image viewer. If it still looks crisp, you're set.

A Yes, the output belongs entirely to you. Your source image is your property, and the generated icons inherit whatever rights you hold for that image. No watermarks, no hidden fees, no attribution required from the tool itself. If you're a designer delivering to a client, just include the ZIP in your asset handoff and note that the files were produced with this generator. One practical tip: keep your original 1024x1024 source archived separately, because you'll want it if the client ever requests tweaks.

A Stick to high-resolution PNG or JPEG files for your source upload. Vector formats like SVG aren't accepted directly by the script, so export a 1024x1024 pixel PNG before dropping it into the box. Avoid JPEGs with heavy compression artifacts because those blurry edges scale down terribly across your tiny notification badges. Clean vector shapes convert into crisp 16px assets every single time.
