Frequently Asked Questions

Which Mermaid diagram types are supported?

All diagram types supported by the current Mermaid release: flowcharts, sequence diagrams, class diagrams, state diagrams, entity-relationship diagrams, Gantt charts, pie charts, and more.

How does the share feature work?

Clicking Share uploads your diagram source to our server and generates a short URL. Shared diagrams are stored for 30 days, after which they are automatically deleted.

Can I export the diagram as an image?

Yes. Use the Download SVG button to save the rendered diagram as a scalable vector file. SVG can be opened in any browser or vector editor and scaled to any size without quality loss.
