The case for JPEG XL
Beautifully written article -- I couldn&#x27;t agree more. From my personal point of view the biggest impact are:<p>1) e-commerce textures such as cloths are more faitfully represented -- more trust in e-commerce, more revenue<p>2) more equity for selfies, people-of-color skin is better represented in JPEG XL, selfies in general look more people like with less smoothing of skin performed at compression stage -- I&#x27;m a great friend of the idea that filtering should not be built into the compression so that all kinds of images can be transmitted<p>3) more compression, faster and cheaper to load<p>4) better progression -- unlike I believe AVIF does, JPEG XL progression does not impose more decoding cost for sequential, progression does not make compression density worse<p>5) thermal camera support -- I believe thermal cameras have huge ecological and cost optimization opportunities and more phones should have thermal cameras in them to facilitate the shift away from fossil fuels<p>6) small images -- thumbnails and sprites etc. do not necessarily need spriting with JPEG XL. That is a nice increase in system level simplicity. JPEG XL overhead is about 10-20 bytes whereas AVIF overhead seems to be 600 bytes or so.<p>7) &#x27;it just works, no surprises&#x27; -- the worst case image quality degradation in any quality setting are much less severe and much less common than in other formats
