How do I save my diagrams?

Mermaid Viewer allows users to download their creations directly from the editor. After composing a diagram, click the “Export” button and choose a format such as SVG, PNG, or PDF. Each format can be customized for resolution, DPI, and light or dark theme prior to saving, ensuring the file is ready for archival or presentation use.

How do I share diagrams with my team?

To share a diagram, simply copy the unique share link generated by Mermaids Viewer. Past this link into an email, chat, or collaboration platform. Recipients with the link can open the diagram in their browser, edit if permissions are granted, or download it in their preferred format without requiring any installation.

Mermaid Viewer supports a comprehensive set of diagram types that are fully Mermaid‑compatible. These include Flowchart, Sequence Diagram, Class Diagram, State Diagram, ER Diagram, Gantt Chart, Pie Chart, Requirement Diagram, Git Graph, C4 Diagram, Mind Map, and Timeline diagrams.

Users can access the editor from any device—Windows, macOS, Linux, or mobile—simply by navigating to the Mermaid Viewer website.

How do I export high‑quality diagrams?

High‑resolution exports are achieved by selecting the “Export” option and choosing a format like SVG, PNG, or PDF.

For premium plans, high‑res PNGs are watermark‑free, and additional formats such as JPG and SVG are available.

Can I collaborate on a diagram in real time?

Mermaid Viewer offers real‑time collaboration tools. By sending a live‑edit link, multiple users can edit the same diagram simultaneously. Changes are reflected instantly for all participants, eliminating version conflicts and streamlining teamwork on shared architectural or process diagrams.

Is my data stored on the server?

Mermaid Viewer is designed with privacy in mind. All diagram data and code remain within the user’s browser session. The platform does not store any user-generated content unless the user explicitly opts to save a diagram through a paid plan’s version history feature. This ensures that sensitive project information stays protected and private.

How can I use Mermaid Viewer with VS Code?

Mermaid Viewer integrates with VS Code through an official extension. Once installed, the extension allows you to preview Mermaid diagrams directly within the editor, providing a live preview pane that updates as you type. It also supports exporting to multiple formats and leveraging the same AI generation features available on the online platform.
