Converting AVIF to WebP lets you take advantage of WebP's 25-35% smaller than jpeg with comparable perceived quality. AVIF files (AV1 Image File Format) can be converted to WebP (Web Picture 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. WebP (Web Picture Format, introduced in 2010) uses VP8 (lossy) / VP8L (lossless) compression. AVIF browser support: All modern browsers (Chrome 85+, Firefox 93+, Safari 16.4+). WebP browser support: All modern browsers (Chrome, Firefox, Safari 14+, Edge).
The quality impact depends on the specific settings used during conversion. WebP preserves full quality with lossless compression.
Typical AVIF file size: A 12MP photo at medium quality: ~1-2 MB. Typical WebP file size: A 12MP photo at quality 80: ~2-3.5 MB.
Always keep your original AVIF file as a master copy. Convert to WebP only for distribution. If you need to make changes later, work from the lossless original to avoid compounding compression artifacts.
