Your app icon is the first impression users have of your app — on the App Store listing page, on their home screen, and in search results. A well-designed icon at exactly the right dimensions for both iOS and Android is essential for a professional-looking app submission. At imgresizr.com, you can resize your icon to all required app icon dimensions, completely free.

How to Resize App Icons at imgresizr.com
Start with your master icon design at 1024×1024px — the largest size needed for the App Store. Upload to imgresizr.com. Use the Resize tool to generate each required size from this master. For iOS, you need: 1024×1024px (App Store), 180×180px (iPhone @3x home screen), 120×120px (iPhone @2x), 87×87px (iPhone @3x Spotlight), 80×80px (iPhone @2x Spotlight), 60×60px (iPhone @1x), and 58×58px (Settings @2x). For Android, start with 512×512px for Play Store and generate 192×192px, 144×144px, 96×96px, 72×72px, 48×48px, and 36×36px for the various screen density buckets. Export all as PNG — app icons require PNG format for both platforms.
App Icon Design Tips
- Design at 1024×1024px and always scale down — never scale up from a small source
- Test your icon at 60×60px — if it is not recognisable at this size, the design needs simplifying
- iOS clips icons to a rounded rectangle automatically — keep important elements away from corners
- Avoid text in app icons — it becomes unreadable at small display sizes
- Use a flat design with minimal gradients for the best cross-device appearance
