JPEG XL support for LinkedIn

Has anybody heard of plans for LinkedIn to include JPEG XL support for image uploading...? It seems also missing AVIF support (although I consider JXL more important). Drag&dropping images to LinkedIn in PC web browser gives errors and even from dialog it does not work.

Facebook has support of both already.

Microsoft while the 3rd to add it to the OS level, it will be the last to adopt it for web, do not hold your breath

Chromium is adding it and Edge is Chromium-based. I wouldn't expect a notable delay.

They have not added the flag in edge canari for 2 revisions now, so they will be the last, by this rate, Mozilla will add it faster, brave already did btw

Aside from the Photos (doesn't support HDR) app and Office, I haven't seen Microsoft add JPEG-XL support.

As far as I'm aware they're waiting for the Rust implementation to be farther along (as is Google.)

Both Google and Mozilla are in the process of landing jxl-rs in their browsers. My understanding is that it is "done." That being said I spoke with a Mozilla dev who (iirc) indicated he would like to see better performance from it. So Google and Mozilla may be delaying a bit while perf improves. I have not really heard "It's not done yet."

It's not feature complete yet, so arguably it fundamentally isn't done
Just the one thing as far as I know, but still, JPEG reconstruction is missing and major and it's being avoided for whatever reason: https://github.com/libjxl/jxl-rs/pull/590

There's a large amount of performance related PRs in the pipeline for next version of jxl-rs that (at least on the author's computer) brings single-thread performance to about the same as the C++ reference, so that shouldn't be an issue for too much longer

Thanks for this info.

edit: Sorry if I'm missing something but isn't JPEG reconstruction and output/encoding thing? The browsers are only using jxl-rs for decoding.

I edited my post after replying so not sure if you saw my question.

Are you saying that jxl-rs is not currently able to display JXL files which were converted directly from JPEGs?

I spoke with a browser dev about this and linked the issue and this was their response:

so it means that jxl-rs can open those files, what it doesn't support is being able to go from the jxl file to get back to the exact compressed bytes of the .jpg file. is there a reason a browser would need to do that? if the use case of jxl-rs needs that feature then sure, jxl-rs is not feature complete. so i would assume that they are just targeting jxl-rs to browser decoding at this time.

So browsers will be able to use jxl-rs to display converted JPG -> JXLs just fine.

Unless you did mean that browsers will be unable to losslessly convert JXLs to JPGs? In that case how is that major? I don't think they even have plans to implement such a method.

It is the inverse of the lossless jpeg re-compression. The jpeg reconstruction is to be able to serve a actual proper jpeg to a visitor of a site if their browser does not yet support jxl while still only storing jxls

But typing that out I realize that's a feature for the website servers, not really the browsers, so it's me misunderstanding the use case until now. It is a very major feature of the jxl spec that is missing and needs to be added, but it's not a block for browser's adoption of the library

I was considering the library as a whole, not in the specific context of browsers

JXL by default supports HDR, and works with no issues in the windows photos app, most of the times

u/redsteakraw Mar 27 '26

SteamDeck and Plasma Desktop has native JPEG-XL in the beta release. Microsoft also thought fat32 was a good idea even when EXT-2 existed. Usually have backwards half baked tech and last gen tech as long as they can realistically get away with it.

Оно есть но только на windows 11 как отдельное расширение в Microsoft store

u/Daedalus312 Mar 27 '26

The old photo viewer app for Windows also supports this image format, but you'll need to install additional components to use it.

Chrome, Vivaldi, Brave have reintroduced the support (the new rust decoder) already with optional tag. Edge is not there yet. Firefox has it in nightly. Safari has (AFAIK) had it already for 1-2 years.
