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.

FAQ

VSI to IFF Conversion

What are VSI files?

VSI (Virtual Slide Image) is a proprietary whole-slide imaging format developed by Olympus for digital pathology and microscopy. It stores high-resolution scanned slides with multi-layer, multi-resolution data for medical and research applications.

What are IFF files?

IFF is an old image format associated with Amiga computers — a brand connected to Commodore, which used to be popular in the 1980s and 1990s. Commodore was one of the first types of personal computers to gain wide popularity among home users. An IFF file most likely contains an image that was created or edited using an image handling program on an Amiga computer.
