Browsers with activation
Converters

- Photostack - Open-source batch photo editor
- ExifTool – Official JPEG XL support added in version 12.25.
- darktable since version 4.2 - Open source photography workflow application and raw developer
- 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
- Squoosh App - Multiplatform desktop app to optimize, resize, compress and convert your images.
