Browse for files, drag them in, or add entire folders at once. reaConverter queues everything automatically.
3. Select JXR as output format
Pick JXR as the output format. Set the destination folder and optionally configure resolution, quality, or file naming.

Start the conversion with one click. reaConverter handles everything and notifies you when it's done.
When the batch finishes, your JXR files are ready in the destination folder you chose earlier.
What changes when you convert JP2 to JXR
JP2 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.
