Key Features
Native Mermaid
Flowcharts, sequence, class and state diagrams render automatically — no setup.
Vector-sharp
Diagrams export as SVG, so they stay crisp at any zoom and print resolution.
No plugins
Most converters need an extension or config for Mermaid. Here it just works in the browser.
100% private
Conversion runs entirely in your browser. Nothing is uploaded — your content never touches a server.
Diagrams that just work
In tools like VS Code or Pandoc, rendering Mermaid usually means installing an extension or wiring up a filter. This converter renders Mermaid natively, turning your code blocks into clean vector diagrams in the live preview and the final PDF.
Document your architecture
Keep diagrams alongside your prose in a single Markdown file — flowcharts for request paths, sequence diagrams for handshakes, state charts for lifecycles — and export the whole thing as one polished PDF for reviews and onboarding.
