MERMAID → PNG
Render Mermaid diagrams to PNG
Paste Mermaid syntax, preview live, and export a crisp PNG. Flowcharts, sequence diagrams, class diagrams and more — with colors that match your theme. Free, no sign-up, runs entirely in your browser.
Why export Mermaid as a PNG?
Mermaid is the fastest way to describe a diagram in text — but most places you want to share it (X Articles, slides, docs, issues) can't render Mermaid source. Exporting to a PNG gives you a portable image that looks identical everywhere, with no live renderer required.
What you get
- Supports flowcharts, sequence, class, state, ER, and Gantt diagrams
- Live preview as you type — catch syntax errors instantly
- Diagram colors stay in sync with your light or dark theme
- High-resolution PNG, ready to copy or download
- Runs fully in-browser — nothing is uploaded to a server
HOW IT WORKS
Convert Mermaid to PNG in three steps
Write your Mermaid diagram
Open the MD2X editor and add a ```mermaid code block with your diagram definition. The live preview renders it as you type.
Review the rendered diagram
Check the preview panel. The diagram uses theme-synced colors, so it matches whether you're in light or dark mode.
Copy or download the PNG
Grab the rendered diagram from the Assets panel — copy it to your clipboard or download the PNG to embed anywhere.
