AVIF vs WebP: best format for smallest file size
AVIF is newer and often beats WebP on compression. WebP has slightly broader support. For most sites, either beats JPEG.
Compression efficiency
AVIF can be 20–30% smaller than WebP at similar quality for photographic content. Ideal for hero images and galleries where every kilobyte counts.
Encoding time
AVIF encoding is slower in the browser than WebP. For large batches, WebP may be faster; for single important assets, AVIF is worth trying.
Support
Chrome, Firefox, and Safari support AVIF. Always keep WebP or JPEG as a fallback strategy for email and older clients.
