Convert Mermaid to SVG

SVG is the best format when you need infinite scaling: print, design tools like Figma, or docs sites that embed vector images. The exported file embeds its fonts as data URLs, so it renders identically everywhere — even inside an <img> tag that can't load external resources.

How it works

1. Paste (or write) your Mermaid code in the editor — the preview renders live.
2. Check the preview. If you see a syntax error, fix the highlighted line or open the code in the full editor and use AI repair.
3. Click “Download SVG”. You get a self-contained vector file with fonts embedded.

Frequently asked questions

How do I convert a Mermaid diagram to SVG?

Paste your Mermaid code into the converter above and click Download SVG. Mermaid.js renders the diagram in your browser and the SVG is serialised with its fonts embedded, so the file is fully self-contained — no signup or upload required.

Is this converter free?

Yes, the converter is free and requires no account. If you want to keep editing the diagram, the 'Open in editor' button takes the same code into MermaidCreator's free visual + code editor.

Is my diagram uploaded to a server?

No. The conversion runs entirely in your browser: Mermaid.js renders your code to SVG locally and the download is produced on your machine. Your diagram code never leaves your computer.

Can I edit the exported SVG?

Yes. The export is a standard SVG file that opens in Figma, Illustrator, Inkscape, or any text editor. For structural changes it's usually faster to edit the Mermaid source instead — open the code in the MermaidCreator editor, change it visually or in code, and re-export.
