Visio File Viewer (VSD, VSDX) Online
Visio files are a closed Microsoft format, and without Visio a .vsd or .vsdx usually opens nowhere: Windows shows only an icon, and Microsoft’s own Visio Viewer only ever worked inside Internet Explorer. Inside this page runs libvisio, the import library LibreOffice Draw relies on for Visio diagrams, built for WebAssembly. It handles all three generations of the format: binary .vsd from Visio 2000 – 2019 (and older Visio 1 – 5 files), .vdx XML drawings from Visio 2003 – 2010, and .vsdx packages from Visio 2013 and later. Pictures pasted into the diagram as Windows metafiles (clip art, network equipment icons) and embedded Excel tables are drawn too, and the preview Visio saved into the file is shown next to the diagram for comparison.

Preview from the file
Visio stores a small thumbnail of the first page whenever it saves a file; it is shown here before the diagram itself has been parsed.
The diagram is read by libvisio (MPL-2.0).
