Create UML diagrams from a plain text language and render them in different formats. More information: https://plantuml.com/en/command-line.

  • Render diagrams to default format (PNG):

plantuml {{diagram1.puml}} {{diagram2.puml}}

  • Render a diagram in given format (e.g. png, pdf, svg, txt):

plantuml -t {{format}} {{diagram.puml}}

  • Render all diagrams of a directory:

plantuml {{path/to/diagrams}}

  • Render a diagram to the output directory:

plantuml -o {{path/to/output}} {{diagram.puml}}

  • Render a diagram without storing the diagram’s source code (Note: It’s stored by default when the -nometadata option isn’t specified):

plantuml -nometadata {{diagram.png}} > {{diagram.puml}}

  • Retrieve source from a plantuml diagram’s metadata:

plantuml -metadata {{diagram.png}} > {{diagram.puml}}

  • Render a diagram with the configuration file:

plantuml -config {{config.cfg}} {{diagram.puml}}

  • Display help:

plantuml -help
