Technical note

VSI to PSD: what carries over and what does not

VSI 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. PSD 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. PSD is lossless, so nothing further is discarded during conversion. What it cannot do is restore detail that VSI compression already removed, and the output file will usually be considerably larger.

I needed to convert my pathology slides (VSI format) to standard images for a research paper. reaConverter handled this smoothly - it's much faster than the default Olympus software and maintains decent image quality. The batch processing saved me hours of work.

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.
