Reading up on AVIF

JPEG XL underperforms AVIF in lossy compression and decode speed, making it unnecessary for the Web despite advantages for non-web use cases like professional photography.

Chrome uses JPEG partial IDCT scaling to decode only low-frequency data when rendering images at small scales, causing icons to render thicker due to lost edge detail, a behavior not shared by Firefox.

Google's Chromium team reversed its decision to drop JPEG XL support, now planning to implement it in Blink, which could make it a de facto standard for images.
