WebP vs AVIF: what changes
| WebP | AVIF | |
|---|---|---|
| Type | Raster (pixels) | Raster (pixels) |
| Compression | Lossy or lossless | Lossy or lossless |
| Transparency | Yes | Yes |
| Animation | Yes | Yes |
WebP is a modern raster format from Google that does both lossy and lossless compression, supports transparency and animation, and runs about 25–34% smaller than JPEG at the same visual quality (per Google's own compression study).
AVIF is the newest mainstream raster format, built on the AV1 video codec. It does lossy and lossless compression with transparency and HDR, and is typically about 20% smaller than WebP — roughly half the size of an equivalent JPEG.
Transparency is preserved, since both WebP and AVIF support an alpha channel. AVIF is typically about 20% smaller than WebP and roughly half the size of an equivalent JPEG.
When to convert WebP to AVIF
Converting WebP to AVIF can shave off roughly another 20% in size while keeping transparency, worth it on a site already chasing the smallest possible images.
Good to know: Both are already efficient, so the saving is incremental, and AVIF's slower encoding plus slightly narrower app support mean it isn't always worth re-converting existing WebP.
