So far following apps support JPEG XL:

Browsers with activation:

Converters:

Other:

• Thunderbird (Email client): To enable JPEG XL support: Tools -> Options -> Advanced -> General: Click on button Config Editor: Manually set image.jxl.enabled to true.
• Photostack - Open-source batch photo editor
• ExifTool – Official JPEG XL support added in version 12.25.
• GIMP – With 2.10.32 the JPEG XL file format support was backported from the 2.99.8 development release, so far only with import ability (unofficial PPA for Ubuntu 21.10+, sudo apt install libjxl-gimp-plugin needed to get JPEG XL support).
  The libjxl repository includes a plugin for 2.10+.
  There is another plugin for development GIMP 2.99.
• ImageMagick – toolkit for raster graphics processing
• FFmpeg – multimedia framework, via libjxl
• Qt / KDE apps - via KImageFormats
