Browse for files, drag them in, or add entire folders at once. reaConverter queues everything automatically.

3. Select JP2 as output format
Select JP2 from the output format list and set your destination folder. You can also adjust quality and compression settings.

When the batch finishes, your JP2 files are ready in the destination folder you chose earlier.
RAW to JP2: what to expect from the conversion
RAW files hold unprocessed sensor data, so white balance and exposure are still adjustable. Converting to JP2 bakes those decisions into the pixels, and highlight recovery is no longer available afterwards. Set white balance and exposure before the run rather than after.
