Technical note

VSI to PS: what to expect from the conversion

PS is a page format, so each VSI image is placed on a page rather than converted into something else. Two settings decide how the result looks: the DPI, which fixes how large the image sits on the page, and whether a batch becomes one file per image or a single merged document. reaConverter can do either.

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.
