VSI to WEBP Conversion: FAQ

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 WEBP files?

WebP is an image file format released by Google in 2010 with the aim of challenging the leading positions of JPG and PNG in the domain of storing and transferring digital images. The purpose of the WebP format is to improve the speed of browsing by offering the same quality as JPEG or PNG, but in a smaller size. WebP images can contain both lossy and lossless compression. They continue, however, to be incompatible with some image viewers and browsers, and are often described by analysts as "work in progress" — a format that still needs to be developed.
