How to Convert Multiple TIF Images to JXL?
1. Download and Install reaConverter Lite
reaConverter Lite is quick to download, easy to install, and ready to launch in seconds. This lightweight, standalone software is highly efficient at handling a wide range of batch image conversions.

2. Load your TIF files
Open reaConverter and add your TIF files. You can load individual files, entire folders, or even nested subfolders.
Drop your TIF files into the window or use File menu to browse and select folders.
3. Select JXL as output format
Choose JXL as the target format. Pick a destination folder or let reaConverter save files alongside the originals.
4. Start TIF to JXL conversion
Hit Convert and let reaConverter do the work. The progress window shows status for each file in real time.
After conversion, find your JXL files in the output folder. Click 'Show converted files' to open it directly.
TIF to JXL: what carries over and what does not
TIF stores pixels without compression loss and JXL does not, so this is a one-way step. Choose a high quality setting, and avoid converting the same file back and forth, because each pass compounds the artefacts. TIF files are often prepared in CMYK for print, and JXL is an RGB format. Colours are converted between the two spaces during the run, and saturated print colours can shift visibly. If the output is heading back to print, keep an untouched copy of the original.
