Question 1

What is Mermaid and how does it work?

Accepted Answer

Mermaid is a text syntax for diagrams. You write steps and connections as plain text, and the editor renders a visual diagram (for example flowchart or sequence). It is ideal for docs, wikis, and repos because the source is easy to version control, review, and maintain.

Question 2

Does ToDiagram show a live preview for Mermaid?

Accepted Answer

Yes. Type Mermaid syntax and see the diagram update instantly in the same window. ToDiagram supports both flowchart and sequence diagrams.

Question 3

How do I export Mermaid diagrams?

Accepted Answer

Use one click export to SVG or PNG. SVG is vector based and stays sharp at any size. PNG works well for screenshots, slide decks, and tools that prefer raster images. You can set background and scale for clean embeds.

Question 4

Is my Mermaid diagram data private?

Accepted Answer

ToDiagram runs locally in your browser. Your text and diagrams are processed on the client and are not sent to servers unless you choose to save to your account or share a link. This keeps drafts and sensitive docs private by default.

Question 5

Do I need to install anything?

Accepted Answer

No. Open ToDiagram in a modern browser and start typing. There are no extensions or build steps. This keeps setup simple for you and your teammates.

Question 6

Can I collaborate and share diagrams?

Accepted Answer

Yes. Save to the cloud to create shareable links or use team workspaces. Teammates can open the same diagram, view it in the browser, and export assets for docs and wikis.

Question 7

Can I import existing Mermaid code?

Accepted Answer

Yes. Paste your Mermaid text into the editor and it will render immediately. You can continue editing, change themes, and export new assets without changing your original source.

Question 8

How large can my diagrams be?

Accepted Answer

There is no hard size limit. Performance depends on your device. ToDiagram is optimized for large documents and remains responsive with smooth pan and zoom in common cases.

Question 9

Does ToDiagram support themes and dark mode?

Accepted Answer

Yes. Switch between light and dark themes and adjust styling for readability. The visual design aims for accessible typography and balanced contrast so diagrams remain clear on screen and in print.

Question 10

Is ToDiagram free to use?

Accepted Answer

You can start in the browser for free. Advanced features like cloud save and team sharing are available on paid plans. You can create and export diagrams without installing anything.
