PNG and WebP are rasterized in your browser from the SVG preview. Use 2× or 3× scale for sharp images in docs and wikis. SVG keeps vector quality and transparent backgrounds.

What is Mermaid?

Mermaid is a text-based diagramming language. Instead of dragging shapes in a GUI, you write plain-text definitions that render into SVG diagrams. It is widely used in GitHub READMEs, Notion, Obsidian, Confluence, and developer documentation because diagrams stay in sync with code and can be diffed in version control.

Keeping diagrams in sync

Server networks, plugin developers, and hosting teams use diagrams to explain architecture to staff and players. Write the diagram as text in your repo, export an image here for platforms that do not render Mermaid natively, and keep the source in sync when your network changes. Pair vote flows with our Votifier Tester and maintenance schedules with the Cron Generator.

Frequently asked questions

Does GitHub render Mermaid automatically?

Yes — GitHub renders Mermaid in Markdown code blocks. For Discord, older wikis, or PDF exports that do not support Mermaid, use this tool to generate a PNG or SVG image instead.

Why is my exported PNG blurry?

Increase the scale to 2× or 3× before exporting. Raster formats encode a fixed pixel grid — higher scale produces more pixels and sharper text on retina displays.

Can I paste Mermaid from ChatGPT or Notion?

Yes. Paste the raw Mermaid source (without markdown fences) into the editor. If the source is wrapped in ```mermaid blocks, remove the fence lines first.
