Support for JPEG XL?


Apologies if this question has been asked before (I’m new to the forum and still finding my way around), but are there any plans to provide JPEG XL support in future versions of RawTherapee?

Keep an eye on this:

JPEG XR (*.jxr) file format support · Issue #6612 · Beep6581/RawTherapee · GitHub

It also mentions a possible workaround.


I read too fast and indeed started comparing apples and oranges…

My bad, sorry!

Er, JPEG XR and JPEG XL are apples and oranges…

There is, however JXL import/export · Issue #6273 · Beep6581/RawTherapee · GitHub



Sorry; I should have provided a bit more context to my question: I was mainly enquiring about JPEG XL export support - I’ll take a look over at GitHub via the link you’ve provided.

Thanks again - much appreciated.

I also think that export is especially important, as it can save a lot of space needed by the resulted images.
Import is not as important now as cameras do not save to this format jet.

Dark Table seems to support jxl import and export, so one can see how they implemented this.
