Technical note

How SCN and DDS differ in practice

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. DDS 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 DDS 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.

What people say after the first batch

Last updated on September 28, 2026
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!

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.

FAQ

SCN to DDS Conversion

What are SCN files?

The Leica SCN file format is a proprietary digital pathology image format used primarily by Leica Microsystems for storing high-resolution whole-slide images (WSI) generated by their slide scanners, such as those in the Leica Aperio series. These files are commonly used in histology, pathology, and biomedical research for viewing, analyzing, and sharing scanned tissue samples.

What are DDS files?

DDS (DirectDraw Surface) is an image file format that usually contains texture data, cubic environment maps or other type of data compressed using the S3TC (S3 Texture Compression) algorithm. The DDS format was first associated with Microsoft's DirectX 7.0 and later on with DirectDraw, a tool for accelerating the rendering of graphics in various applications. DDS is a container file and can be decompressed using a graphics processing unit (GPU).
