  Qt plug-in to allow Qt and KDE based applications to read/write JXL images.

KDE's KImageFormats plugin for Qt supports JXL, though this may not be enabled on your distro. If it is, Qt image viewers like Gwenview can be used to view JXL files. If not, there's another plugin available, which may be available in your distro or you can build it yourself, which also enables programs like Gwenview to use JXL.
