Convert an image to Mermaid with AIFrequently asked questions
How do I convert a draw.io file to Mermaid?
Drop your .drawio file onto the box above. It's converted immediately and the Mermaid code appears in the editor, where you can edit it and download the result as PNG or SVG. No account needed.
Does this work with diagrams.net files?
Yes. draw.io and diagrams.net are the same application and use the same .drawio format. Files saved from either one work here, including compressed files saved by the desktop app.
Which diagram types are supported?
Flowcharts, class diagrams, entity-relationship diagrams, sequence diagrams, state diagrams, component diagrams and network diagrams. The diagram type is detected from the file's contents and the matching Mermaid syntax is generated automatically.
Is the conversion accurate?
A .drawio file stores its nodes and edges explicitly as XML, so the conversion reads real structure rather than inferring it from an image. That makes it deterministic: the same file always produces the same Mermaid code. Very heavily styled diagrams may lose purely visual formatting that Mermaid has no equivalent for.
Why convert draw.io to Mermaid?
Mermaid is plain text, so it lives in version control, reviews cleanly in pull requests, and renders natively on GitHub and GitLab. That makes it a better fit than a binary diagram file for documentation that sits alongside code.
Is my file uploaded or stored?
Your file is sent to our server, parsed, and returned as Mermaid code. We don't store the file itself. If you're signed in, the resulting Mermaid code is saved to your conversion history so you can find it later; if you're not signed in, nothing is kept.
