Why WebP to AVIF?
WebP is already a modern format with good compression, but AVIF takes it further. Expect another 15-25% size reduction when converting WebP to AVIF at equivalent quality.
This conversion makes sense when you're optimizing for the absolute smallest file sizes. For image-heavy sites where every kilobyte counts, AVIF is the current gold standard.
The trade-off is slightly lower browser support (93% vs 97%) and slower encoding. But if you're already using WebP, you can serve AVIF to browsers that support it and fall back to your existing WebP files.
Frequently Asked Questions
Yes, typically 15-25% smaller at equivalent quality. Both are efficient modern formats, but AVIF edges ahead in compression.
Animated WebP will be converted to a static AVIF (first frame). AVIF does support animation, but browser support for animated AVIF is still limited.
Consider keeping WebP as a fallback for older browsers. Use the HTML picture element to serve AVIF to browsers that support it, WebP to others.
