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
