Exciting #avif news – libaom’s tune iq (derived from SVT-AV1-PSY’s Tune 4) is used across The Guardian’s website now. They say they serve mostly AVIF, with JPEG XL shipped when supported. Very exciting stuff! Thanks @juliobbv.bsky.social!

Introducing Iris-WebP, a better WebP encoder: halide.cx/iris/index.h...

Iris offers up to >20% better compression than libwebp, and trades blows with libaom for AVIF.

My goal is to build an image-first encoder ecosystem for the modern Web, so that new web image codecs aren't generally superfluous.

Updated numbers for Eve-AV1 & Eve-VP9 are public! The last time they were updated was around 2019, so this should give a more relevant look at how they perform.

It takes a lot to improve a mature video encoder, and I'm very impressed with the Eve lineup. Shout-out @luctrudeau.bsky.social!
