Converting AVIF to ICO lets you take advantage of ICO's stores multiple resolutions (16x16 through 256x256) in one file. AVIF files (AV1 Image File Format) can be converted to ICO (Icon File Format) for better compatibility, smaller file sizes, or access to features that AVIF does not support.
AVIF (AV1 Image File Format, introduced in 2019) uses AV1 intra-frame (lossy and lossless) compression. ICO (Icon File Format, introduced in 1985) uses None (BMP payload) or PNG payload compression. AVIF supports animation, but ICO does not. Only the first frame will be preserved during conversion. AVIF browser support: All modern browsers (Chrome 85+, Firefox 93+, Safari 16.4+). ICO browser support: Universal.
The quality impact depends on the specific settings used during conversion. ICO preserves full quality with lossless compression.
Typical AVIF file size: A 12MP photo at medium quality: ~1-2 MB. Typical ICO file size: A multi-size favicon (16+32+48+256): ~15-100 KB.
For the best conversion results, always start from the highest quality source file available. Converting from a previously compressed file compounds any existing compression artifacts. When in doubt, use higher quality settings — you can always re-convert at lower quality later, but you cannot recover quality that has been lost.
