How to Convert Multiple JXR 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. Plus, it lets you apply essential image editing options — such as resizing, rotating, or adjusting quality — during the conversion process.
2. Load your JXR files
Add JXR files to reaConverter. One file or a thousand, the process is the same. Everything runs locally on your machine.
You can drag-and-drop files, browse to a folder, or add entire directory trees including subfolders.
3. Select JXL as output format
Select JXL from the output format list and set your destination folder. You can also adjust quality and compression settings.
4. Start JXR to JXL conversion
Click the Convert button to start. reaConverter will process all your files with the settings you selected.
When finished, your new .jxl files will be waiting in the destination folder.
Before you convert JXR to JXL
JXR and JXL both compress by discarding data, so this is a re-encode rather than a copy. The output is built from already-compressed pixels, and the artefacts of the first encode are carried into the second. Use a high quality setting, and convert from the original whenever you still have it.
