About PLANTUML files

A .PLANTUML file is a plain text script used to define Unified Modeling Language (UML) diagrams via code rather than drag-and-drop graphics. These files contain domain-specific syntax - typically bookended by @startuml and @enduml tags - that describes the logic for sequence diagrams, use cases, class diagrams, and even Gantt charts. While highly efficient for version control and developers, the raw format is essentially useless for presentation purposes. You cannot embed a .PLANTUML file directly into a PPTX slide or a DOCX report, and it will not render in standard image viewers like Microsoft Photos or Apple Preview. To visualize the diagram, the file must be "compiled" or rendered using the Java-based PlantUML engine, often requiring Graphviz dependencies installed locally. To share your diagrams with non-developers or stakeholders, the standard workflow is converting these text definitions into portable visual formats. For web documentation and slides, converting to PNG is the most compatible choice. For high-fidelity printing or infinite scaling, SVG or PDF is preferred. In some legacy documentation contexts, these files can even be converted to ASCII Art text blocks.

Convert.Guru analyzes your PLANTUML file, detects the exact format, and lets you read the text inside.

Users also converted PUML, TXT, SVG, UML, PLUM, PU, WSD, PNG, DRAWIO, MD, XML, XMI and WSDL files.

The PLANTUML 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 PLANTUML converter.
