Convert MMD to PLANTUML
Fast, free, and secure MMD to PLANTUML conversion. No registration required.
No app to install, no account to create — just open this page, drop your mmd file, and get plantuml output in seconds. What makes this conversion useful: Mermaid Diagram gives you renders directly in GitHub, GitLab and many Markdown viewers, but PlantUML Source unlocks PlantUML diagrams using self-documenting extension — something Mermaid Diagram struggles with (limited styling options compared to dedicated diagramming tools). This is one of the most frequently used conversions on Xonvert, with 510 daily conversions on average. The entire conversion pipeline runs in a sandboxed WebAssembly environment for maximum security and performance.
