About Favicon Generator
What It Does
Upload a single image and this tool generates every favicon size a modern website needs — from tiny 16×16 browser tab icons to 512×512 PWA splash screens. Download everything as a ZIP with a ready-to-use HTML snippet.
Generated Sizes
- 16×16 — Standard browser tab favicon
- 32×32 — HiDPI browser tab, bookmarks
- 48×48 — Windows site icon
- 180×180 — Apple Touch Icon (iOS home screen)
- 192×192 — Android Chrome, PWA icon
- 512×512 — Android PWA splash screen
- favicon.ico — Multi-size ICO (16+32+48) for maximum compatibility
Tips
- Use a square image for best results — non-square images are center-cropped
- Start with at least 512×512 pixels for crisp results at all sizes
- Simple, bold designs work best at small sizes
- PNG with transparency is supported
