Every mobile app needs icons — and not just one. Apple and Google each require a specific set of sizes for their platforms, totalling over 20 unique dimensions between them. Manually resizing each one in Photoshop or Figma is tedious. The CachePlex App Icons Generator does it all in seconds, for free.

Why App Icons Matter

Your app icon is the first thing users see on the App Store, Google Play, and their home screens. A crisp, properly-sized icon signals professionalism. A blurry or pixelated one — caused by using the wrong dimensions — can undermine trust before users even open your app.

Both iOS and Android have strict icon size requirements, and submitting the wrong sizes can cause App Store or Play Store rejection.

iOS App Icon Sizes Required by Apple

Apple requires 15 separate icon sizes ranging from 20px (notifications) to 1024px (App Store listing). These include sizes for iPhone, iPad, Spotlight search, Settings, and the App Store itself. Our free app icon generator outputs all 15 sizes with the correct filenames and a ready-to-use Contents.json file for Xcode.

Android App Icon Sizes Required by Google

Android uses a density-based system: ldpi (36px), mdpi (48px), hdpi (72px), xhdpi (96px), xxhdpi (144px), xxxhdpi (192px), and a 512px Play Store icon. Each goes in its corresponding mipmap-* resource folder. Our generator creates the correct folder structure automatically.

How to Generate App Icons for Free

Using the CachePlex App Icons Generator takes under a minute:

  1. Prepare your source image — a square PNG at least 1024×1024px works best. Transparent backgrounds are supported.
  2. Upload it — drag and drop or click to browse. PNG, JPG, and WebP are all accepted.
  3. Choose your platform — iOS, Android, or both.
  4. Click Generate — the tool resizes your image to every required dimension.
  5. Download the ZIP — unzip and drop the folders straight into Xcode or Android Studio.

Tips for a Great App Icon

Start with the largest size (1024px) and design at that resolution. Avoid text in your icon — it becomes unreadable at small sizes. Use bold, simple shapes with strong contrast. Test your icon on both light and dark home screens before submitting.
