TL:DW, JPEG is getting old in the tooth, which prompted the creation of JPEG XL, which is a fairly future-proof new compression standard that can compress images to the same file size or smaller than regular JPEG while having massively higher quality.
However, JPEG XL support was removed from Google Chrome based browsers in favor of AVIF, a standalone image compression derived from the AV1 video compression codec that is decidedly not future-proof, having some hard-coded limitations, as well as missing some very nice to have features that JPEG XL offers such as progressive image loading and lower hardware requirements. The result of this is that JPEG XL adoption will be severely hamstrung by Google’s decision, which is ultimately pretty lame.
Jpeg XL isn’t backwards compatible with existing JPEG renderers. If it was, it’d be a winner. We already have PNG and JPG and now we’ve got people using the annoying webP. Adding another format that requires new decoder support isn’t going to help.
You can't add new and better stuff while staying compatible with the old stuff. Especially not when your goal is compact files (or you'd just embed the old format).
All the cool kids use .HEIF anyway
I use jpeg 2000
Isn't that the same as other newer formats though?
There's always something new, and if the new thing is better, adding/switching to it is the better move.
Or am I missing something about the other formats like webp?
You have to offer something compelling for everyone. Just coming out with yet another new standard™ isn’t enough. As pointed out earlier, we already have:
What’s the point of adding another encoder/decoder to the table when PNG and JPEG are still “good enough”?
PNG and JPEG aren’t good enough, to be honest. If you run a content heavy site, you can see something like a 30-70% decrease in bandwidth usage by using WebP.
My understanding is that webp isn't actually all that bad from a technical perspective, it was just annoying because it started getting used widely on the web before all the various tools caught up and implemented support for it.
It's certainly not bad. It's just not quite as good.
"the annoying webp" AFAIK is the same problem as JPEG XL, apps just didn't implement it.
It is supported in browsers, which is good, but not in third party apps. AVIF or whatever is going to have the same problem.
Forgive my ignorance, but isn't this like complaining that a PlayStation 2 can't play PS5 games?
It's a different culture between PCs can consoles. Consoles are standardized computers - they all have the same* hardware' Game developers can be confident in what functionality their games have access to, and so use the best they can.
PCs in comparison are wildly different from user to user due to being modular: you can pick from many parts to create a computer. As such, devs tend to focus on what most PC's can do and make them optionally better if the PC has access to supporting hardware (e.g. RTX ray-tracing cores).
Besides, video games are drastically complex in comparison to static images 😛
I just wish more software would support webp files. I remember Reddit converting every image to webp to save on space and bandwidth (smart, imo) but not allowing you to directly upload webp files in posts because it wasn't a supported file format.
If webp was just more standardized, I'd love to use it more. It would certainly save me a ton of storage space.
Google's handling of jxl makes a lot more sense after the jpegli announcement. It's apparent now that they declined to support jxl in favor of cloning many of jxl's features in a format they control.
Look it's all actually about re-encumberancing image file formats back into corporate controlled patented formats. If we would collectively just spend time and money and development resources expanding and improving PNG and gif formats that are no longer patent encumbered, we'd all live happily ever after.
JPEG-XL is in no way patent encumbered. Neither is AVIF. I don't know what you're talking about
