About WSD files
The .WSD file extension is highly fragmented, but its most common modern use is as a plain-text source file for PlantUML to generate Unified Modeling Language (UML) diagrams. It is also actively used for proprietary automation projects in WAGO-I/O-PRO CAA, electrical CAD data in WSCAD SUITE, and historically as legacy WordStar documents.
Because the .WSD format shares so many completely different file signatures, operating systems like Windows and macOS constantly struggle to assign a default program. A PlantUML .WSD file is technically just text, but it requires a rendering engine or server setup to visualize the actual flowcharts or class diagrams. Without this environment installed, the file is practically useless for sharing with clients or stakeholders. Proprietary versions like WAGO or WSCAD files pose an even bigger challenge: they require expensive, highly specialized engineering software to open and are notorious for locking users out on mobile devices. Furthermore, legacy WordStar documents use an obsolete binary structure that modern word processors like Microsoft Word cannot natively read.
To make these files accessible, you must convert them into standardized formats. For PlantUML .WSD files, convert to PNG or SVG for seamless web viewing, or PDF for reliable document archiving. If you are dealing with legacy WordStar files, convert them to TXT or DOCX to securely salvage the text. Drag and drop your file to analyze and convert it - free, online, and without installing software.

To convert PDF, DOC, ASC, TODO, NFO, MEMO, README, DOCX, JPG, TXT, NOTE or RTF files to WSD, try PlantUML or another comparable tool in the "UML Diagram Source Code" category.
The WSD Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our WSD converter.
