I think JPEG XL's naming was unfortunate. People want to associate new image formats with leanness, lightness, efficiency.
They're running out of good options, but I hope they stick with it long enough to release "JPEG XP" :-)
There's also a JPEG XE now (https://jpeg.org/jpegxe/index.html), by the way.
What makes jpeg bad is that the compression artifacts multiply when a jpeg gets screen captured and then re-encoded as a jpeg, or automatically resized and recompressed by a social media platform. And that definitely isn’t a problem that has gone away since dialup, people do that more than ever.
Either that or a photo that has been edited from a RAW and is a final version to be posted online.
Though maybe some people think the JPEG committee is now creating spreadsheet formats...
Of all the people who interact with image formats in some way, how many do even know what an image format is? How many even notice they’ve got different names? How many even give them any consideration? And out of those, how many are immediately going to think JPEG XL must be big, heavy and inefficient? And out of those, how many are going to stop there without considering that maybe the new image format could actually be pretty good? Sure, there might be some, but I really don’t think it’s a fraction of a significant size.
Moreover, how many people in said fraction are going to remember the name (and thus perhaps the format) far more easily by remembering it’s got such a stupid name?
* A new lossy image Codec
* A lossless image codec (lossless modular mode)
* An alternative lossy image codec with different kinds of compression artifacts than those typically seen in JPEG (lossy modular mode)
* JPEG packer
Because it includes a JPEG packer, you can use it as such.
(Kidding.)
ISO: "Challenge accepted." [1]
Actually, I remember when JPEG XL came out, and I just thought: cool, file that one away for when I have a really big image I need to display. Which turned out to be never.
Names have consequences.
Honestly, that's exactly what it sounds like to me too. I know it's not, but it's still what it sounds like. And it's just way too many letters total. When we have "giff" and "ping" as one-syllable names, "jay-peg-ex-ell" is unfortunate.
Really should have been an entirely new name, rather than extending what is already an ugly acronym.
WEBP can only do 16,383px per side and the AVIF spec can technically do 65,535, but encoders tap out far before then. Even TIFF uses 32-bit file offsets so can't go above 4GB without custom extensions.
Guess which format, true to its name, happens to support 1,073,741,823px per side? :-)
