SCN to JXL: what carries over and what does not

SCN 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.

"reaConverter handles straightforward SCN-to-TIFF/JPEG conversions efficiently, which is helpful for sharing slides with collaborators who don’t have Leica software. The interface is user-friendly, and I’ve had no issues with standard brightfield images."

"I regularly work with Leica SCN files in my pathology lab, and reaConverter has been a lifesaver when I need to convert them to TIFF or JPEG for collaboration. The batch processing feature saves me so much time, and the output quality remains excellent, no loss of detail even at high magnifications. The software is intuitive, and I appreciate that it preserves metadata during conversion. Highly recommended for digital pathology workflows!"
