JPEGXL literally is able to display images and colors that jpeg and png cannot (32-but floating point, layers, emission independent transparency, spot colors, built im depth maps). It’s not just about compression optimization. So for those use cases standard JPEG and PNG alone will never work. There are “updated” versions of JPEG that support some of these like HDR but those won’t work with any old browser either so back to the same issue.

Yes, but that’s still a niche use case. Web pages look fine using the colors we already have. Somewhat more vibrant colors are a luxury.

Can the human eye even tell the difference? This feels like 8k vs 4k tv.

		> Can the human eye even tell the difference? This feels like 8k vs 4k tv. Even if it cannot, getting the same quality as 'classic' JPEG in fewer bits is still useful. So you have: * better quality in the same number of bits * same quality in fewer bits

		Bottom line it can deliver greater quality at much smaller filesizes. Considering RAM and storage are more expensive per byte now than they have been in years, I think it's incumbent on everyone in a position to do so, to use those resources wisely. WebP and AVIF and HEIC had similar advantages but also some disadvantages (honestly chief disadvantage to WebP in my humble opinion was that nothing except web browsers -- to this day -- seem to support it!). Another important point in its favor is that JPEG XL is designed as a royalty‑free, open standard, and Google provides a perpetual, worldwide, royalty‑free patent license for its reference implementation. Avoiding JXL (once the rollout is sufficiently complete) seems, to me, like still shipping (non-animated) .GIF files where .PNG is better and smaller.

		On an ecommerce site? Who cares. On instagram or anywhere people share photos? Amazing.
