WebP → AVIF, the next notch of compression

For pipelines standardising on AVIF. From lossy WebP sources the gain is real but bounded; the page says so.

Moving existing WebP assets to AVIF makes sense when a site or toolchain has standardised on the newer format. Expectations should stay calibrated: from lossy WebP sources, AVIF's advantage narrows, since both formats have already spent the easy savings, and a second lossy generation is added. From lossless WebP graphics the conversion is clean. Where original masters exist, encoding AVIF from those beats converting derivatives, and this page will not pretend otherwise.

Re-encoding one efficient lossy format into another edges rightward on the scale; from lossless WebP sources the marker stays pinned left.

Questions

How much smaller will AVIF be than my WebP?

From lossy sources, often 10 to 20 percent; from lossless graphics, more. The dramatic AVIF savings quoted online compare against JPG, not WebP.

Is this worth an extra generation of loss?

For a format-standardisation migration, usually yes at these levels. For individual images, only if the destination requires AVIF.

Local processing?

Yes, encode and all.
