What is MermaidRender.com?
MermaidRender.com is a free, interactive live editor for creating and viewing Mermaid.js diagrams. It allows you to quickly write diagram code and preview it in real-time, then export it to various formats including high-DPI print-ready PNG images (up to 700 DPI), SVG vector graphics, and PDF documents.
How do I export high-resolution diagrams?
Select your preferred DPI (e.g., 300 DPI for high quality, or 700 DPI for maximum resolution) and format from the drop-down menu in the top toolbar, then click the Download button. The diagram will be rendered and downloaded directly to your computer.
Is my diagram data secure and private?
Yes. MermaidRender.com is a serverless application that runs entirely inside your web browser. Your Mermaid code and rendered diagrams are never uploaded, stored, or processed on any external servers. Everything stays secure on your local machine.
