When it comes to vis to jpeg conversion, the only one we have found so far is the potential export of Strata Studio 3D files (.vis) to JPEG format, most likely for some kind of preview purpose.
Except for that, this might be a type for generic searches about 'visio to jpeg' or similar queries, but Visio uses .vsdx or .vsd files and not .vis files.
