Free App Icon Generator: Create iOS & Android Icons in Seconds
Every app needs a full set of icons before it can ship — and Apple and Google each demand their own sizes and formats. Resizing one image by hand in a photo editor is slow and error-prone. This free app icon generator does it for you: upload one image, pick your platform, and download every required icon size at once.
There is no sign-up, no watermark, and nothing to install. It works right in your browser, which makes it perfect for developers, indie makers and designers who just want their iOS app icons or Android icons ready now.
What Is an App Icon Generator?
An app icon generator is a tool that takes a single source image and produces the complete set of icon sizes a mobile app store requires. iOS apps need icons for the home screen, Spotlight, settings and the App Store; Android apps need multiple densities from mdpi up to xxxhdpi. Instead of exporting each size manually, the generator creates all of them in one pass, sized and named correctly.
How to Generate App Icons (Step-by-Step)
Creating a full icon set takes less than a minute:
- Step 1: Upload your icon artwork — a square, high-resolution image works best (1024×1024 px is ideal).
- Step 2: Choose your platform: iOS or Android.
- Step 3: Set a background color with the hex color picker and adjust the padding so your artwork sits perfectly inside the icon.
- Step 4: Click generate and download your icons — every required size, ready to drop into Xcode or Android Studio.

Tips for a Great App Icon
Start from a large square image — at least 1024×1024 pixels — so every generated size stays crisp. Keep the design simple and recognizable at small sizes: a single bold shape or letter usually beats fine detail that disappears at 29×29 px. Use the padding control to give your artwork breathing room, and test the background color against both light and dark home screens before you ship.
If you maintain both an iOS and an Android version of your app, generate both sets from the same source image so your branding stays consistent across platforms.
