As the topic, I have changed all of my cd’s artwork to .jxl. jxl has a higher compression rate than png while maintaining image quality.
It also supports dynamic loading. Load the important parts of the image first
Did you try it then with Roon and does it work?
As far as I can tell, No, it does not support .jxl, it does not let me select a .jxl for album art.
Welcome to the Roon community, @Xuanhua_Lin.
I have moved your posts to Feature Suggestions.
However, for Roon to adopt this, I think JPEG XL would need to be more widely used by those distributing digital music.
Chicken egg issue then. Will likely not be used by distributors until a critical amount of third-party software and hardware (players, streaming services, tag editors, catalogs, …) is supporting the format.
Possibly, but AFAIK, only macOS currently supports this natively. Software used for image creation rather than presentation needs to adopt, too.
And there must be a real benefit in it for distributors (yes distributors and not end-users) for even think about forcing any new picture format (which I fail to see for the case of JPEG XL as format for album art in files *). If not, there will be no forcing and a “new” format has to rather genuinely replace an old format in common use (all major graphics libraries in use over some time to bleed into products) so that no additional effort for supporting it is needed.
Note: If I got that right, then “old” JPEG files can be encoded in JPEX XL (without using new features of course) unchanged. * So even with its support it would not mean that images actually make use of new features (seamless transition but no real benefit for the use case at hand).
Picture size doesn’t really matter much compared to hi res or even redbook files. Nor does progressive loading on local storage. I guess there won’t be a rush.
I agree, the new format is really beneficial for digital photography or images that requires lossless compression.
I can’t see a 600x600 px or even 1200x 1200 px cover image needing this any time soon.
I have lots of scaned picture with 1200 dpi. A picture will take about 100MB space. After I converted, it can be reduced to 60-70MB. And a poster may take 1GB to save, I thought it is useful.
My embedded album art ist 500 by 500 pixel for the most part and something like 1200 by 1200 pixel my be the ceiling. These compressed pictures are only a few kilobytes, maybe a megabyte for a big, complex one. Some of them are scanned too.
I means the artwork, such as lyric book, photograph etc
There is no reason for 1200 DPI for the usual printed stuff (printed media usually has far less resolution). Roon also supports PDF for nice collections of scanned content and more – but PDF IIRC does not support JPEG XL as of now. If it does, use that as container.

OK, thanks for your explaination!
