About App Icon Size Guide

Reference guide for all required app icon and favicon sizes across platforms. Includes filename conventions, density labels, and export checklist.

Step by Step

  1. 1 Enter your project name (optional)
  2. 2 Select a platform or view all platforms
  3. 3 Review the required sizes, filenames, and contexts
  4. 4 Use the checklist to ensure you have all required assets

Tips

  • Always start with the largest size (1024px) and scale down
  • iOS requires no transparency and no rounded corners in the source — the OS applies masking
  • Android adaptive icons need a safe zone of 66% for the icon content
  • Web PWA requires at least 192px and 512px icons in the manifest

Frequently Asked Questions

How many icon sizes do I need?
It depends on the platform. iOS needs 13 sizes, Android needs 6, Web/PWA needs about 10 (including favicon and apple-touch-icon), Windows needs 10, and macOS needs 7. For a cross-platform app, you need about 46 icon files total.
What format should app icons be?
PNG is the standard for all platforms. iOS and Android both use PNG. For web favicons, you need both .ico (for legacy browsers) and .png, plus an SVG for modern browsers.
