Converting WebP to AVIF lets you take advantage of AVIF's best-in-class compression: 50% smaller than jpeg, 20% smaller than webp. WebP files (Web Picture Format) can be converted to AVIF (AV1 Image File Format) for better compatibility, smaller file sizes, or access to features that WebP does not support.
WebP (Web Picture Format, introduced in 2010) uses VP8 (lossy) / VP8L (lossless) compression. AVIF (AV1 Image File Format, introduced in 2019) uses AV1 intra-frame (lossy and lossless) compression. WebP browser support: All modern browsers (Chrome, Firefox, Safari 14+, Edge). AVIF browser support: All modern browsers (Chrome 85+, Firefox 93+, Safari 16.4+).
The quality impact depends on the specific settings used during conversion. AVIF preserves full quality with lossless compression.
Typical WebP file size: A 12MP photo at quality 80: ~2-3.5 MB. Typical AVIF file size: A 12MP photo at medium quality: ~1-2 MB.
Always keep your original WebP file as a master copy. Convert to AVIF only for distribution. If you need to make changes later, work from the lossless original to avoid compounding compression artifacts.
