PSA: For images, there's a finally successor to jpeg: JPEG XL (.jxl) - has lossy and lossless mode; is progressive (you can download just the first parts of the bitstream to get a lower resolution image; and other benefits!) https://jpegxl.info/

"Your browser does not support JPEG XL"; I'm sure it's cool technology but whoever is behind it needs to hire developers and advocates to push code to Webkit / Blink to add support for it, else it won't get mainstream adoption.
I really hope it takes off. There was a bit poor timing because widespread AVIF support happened _right_ before and now we need to beg browser vendors to adopt JPEG XL! I hope they don't balk at it for starting introduce too much file format cruft because JPEG XL is really, really something they should implement. It can succeed JPEG as well as PNG (lossless JPEG XL tend to destroy even optimized PNG). I'd much rather abandon AVIF support. It's just one of those annoying single-video-frame-as-a-picture hacks like WebP and HEIF without drive to make them outstanding image formats on their own for photography as well as line art.

The problem with these formats is that they don’t offer enough of an advantage to overcome the disadvantage of have less than the enormous install base of JPEG. Look how much better PNG is than GIF and realize it only succeeded in replacing it (for static images) because of the Unisys patent suits, not because it’s so much better.

As a mobile developer I generally see WEBP getting served to Android devices and HEIC to Apple devices. Is there any advantage to JPEG XL over those? If our app supported older iOS devices, maybe JPEG would be needed as a fallback, but it seems like JPEG XL wouldn't be compatible with old devices anyway, right?

You would just say "10 tosses, all heads" - bam! You've just compressed some data! Easy. I saved you hours of mindfuck lectures. This is obviously an oversimplification, but you've transformed some data into another shorter representation o…

Did they avoid the prohibitive licensing that left JPEG 2000 dead in the water?

Ahh, my favorite kind of technical walkthrough. Love it
Ah ASCII art. Long rows of identical characters. The only thing that actually allowed a dial up modems compression claims to actually live up to the marketing hype....
Don't for get the HTML and other plain text that is sent/received.

I’ll need both Capture One and Lightroom to support whatever gets decided on though, and that could take a while.
Fabrice Bellard's BPG image format uses H.265's keyframe compressor: https://bellard.org/bpg/ Here is a side-by-side visual comparison: http://xooyoozoo.github.io/yolo-octo-bugfixes/#ballet-exerci... Amazing. I ported his BPG decoder to Android ARM for a pornographic app. See my comment history for details. It reduced data transfer by more than 60%.
