Select BMPs from a folder or drag-and-drop them directly into the reaConverter window.

3. Select JXR as output format
Choose JXR for output and set your save location. reaConverter lets you customize quality and apply edits before conversion.

After processing, find all your new .jxr files in the output location. The log shows details for each conversion.
BMP to JXR: what carries over and what does not
BMP stores pixels without compression loss and JXR 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.
