The viewer converts Visio drawings, stencils and templates to a PDF preview, so you can inspect the diagram without installing Microsoft Visio.
Use it for quick checks of VSD, VSDX, VSDM, VSS, VSSX, VSSM, VST, VSTX, VSTM, VDX, VSX and VTX files. After conversion you can open the preview in a new tab or download the PDF.
