This article describes what a VSD file is and how to open a VSD file or convert it to another format.
A file with the .VSD extension is a drawing file created by Visio, Microsoft's professional graphics application. These are binary files that can contain text, images, CAD drawings, charts, annotations, objects, and more.
Visio files are used to create everything from software and network diagrams to flowcharts and organizational charts.
Microsoft Visio 2013 (and newer) saves Visio drawing files with the .VSDX file extension by default. This file extension is XML-based and compressed with ZIP.
