How to Convert Multiple DDS Images to JXR?
1. Download and Install reaConverter
First, grab reaConverter from the download button below. Installation is fast, and the software runs offline — no account or signup needed. reaConverter also includes editing tools: resize, crop, rotate, and more.
2. Load your DDS files
Open reaConverter and add your DDS files. You can load individual files, entire folders, or even nested subfolders.
Drop your DDS files into the window or use File menu to browse and select folders.

3. Select JXR as output format
Choose JXR as the target format. Pick a destination folder or let reaConverter save files alongside the originals.

4. Start DDS to JXR conversion
Hit Convert and let reaConverter do the work. The progress window shows status for each file in real time.

After conversion, find your JXR files in the output folder. Click 'Show converted files' to open it directly.
How DDS and JXR differ in practice
DDS and JXR 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. One DDS file can hold several pages or frames, while JXR holds one image each. reaConverter writes a separate output file per page and numbers them, so a single input can produce a whole folder of results.
