Technical note

SCN to JXL: what carries over and what does not

SCN is a pyramidal whole-slide image: one file carries the same scanned slide at several magnifications, and the largest level can run past 100,000 pixels on a side. JXL holds a single flat picture at one resolution. That makes the magnification the decisive choice, because there is no sensible original size to fall back on here: the full-resolution level of a slide scan is larger than most image software will open at all. 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!

Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch.
