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.

FAQ

SVS to CG4 Conversion

What are SVS files?

SVS is an image format associated with Aperio medical equipment, such as microscopes or scanscopes. Though similar with the TIFF format in terms of features, SVS has a lot less compatibility with regular image viewers and tends to have a very large size. SVS files contain multiple images in a predefined order, including a baseline tiled image, a thumbnail, intermediate "pyramid" images (made up of tiles), an optional slide label image etc.

What are CG4 files?

CG4 is a raster format associated with CALS (Continuous Acquisition and Life-Cycle Support) — a program initiated by the US Department of Defense to capture and link military data.
