AVIF to ICO Converter (transparent, multi‑size favicon)

Convert AVIF to ICO online. Create multi‑size favicons (16–256 px) with transparent or solid background—browser‑based.

Why convert AVIF to ICO

Some environments still expect favicon.ico at the site root. While modern formats are excellent, a multi‑size ICO (16–256) ensures crisp results in Windows and legacy contexts. Use ICO for compatibility, plus Apple Touch PNG and a masked SVG.

Recommended sizes

  • Classic tabs: 16×16, 32×32
  • Hi‑DPI: 48×48, 64×64
  • Windows/large: 128×128, 256×256

Troubleshooting

  • Blurry at 16 px: simplify artwork or use a sharper profile.
  • Caching: append ?v=2 to force reload.
  • Transparency edges: try solid background for tiny sizes.
