By default, all software supports multiple file extensions. OmniGraffle supports at least 7 different file extensions. The basic files that OmniGraffle supports are .VSS. However, not all of the extensions listed on the list are always used to save the effects of work in OmniGraffle. Very often, files with such extensions are used as source data files used by OmniGraffle.
OmniGraffle can be used to convert file formats between the file extensions listed below. You can open a file with one of the file extensions below via OmniGraffle and try to save it in another file format, also supported by OmniGraffle.
