Powerful Features

Activity Diagram Support

Convert PlantUML activity diagrams with start/stop points, actions, conditions, and parallel flows into visual flowcharts.

Sequence Diagram Parsing

Transform sequence diagrams showing interactions between participants into clear visual flow representations.

Condition Handling

Properly convert if/else conditions, switches, and branching logic into visual decision nodes with clear paths.

Loop Recognition

Identify and visualize loops, repeat structures, and iterative processes from your PlantUML code.

Editable Output

Unlike static PlantUML renders, the output is fully editable - move nodes, add labels, change colors, and more.

Multiple Export Formats

Export to PNG for presentations, SVG for high-quality graphics, or Mermaid code for other documentation tools.

Why Choose This Free Tool?

Bridge Code and Visual

Keep your diagrams in version control as PlantUML, then generate visual versions for stakeholders who prefer graphical representations.

Leverage Existing Documentation

Convert PlantUML diagrams already in your codebase or Confluence into editable flowcharts without recreating from scratch.

Collaborate with Non-Developers

Share visual flowcharts with PMs, designers, or clients who may not understand PlantUML syntax.

Customize for Presentations

Convert technical PlantUML diagrams into polished visuals suitable for presentations and reports.

Edit Without Learning New Syntax

Make visual edits to the flowchart without needing to modify the original PlantUML code.

Export to Other Formats

Convert PlantUML to Mermaid for platforms that support Mermaid but not PlantUML, like GitHub markdown.
