How to Add Mermaid Diagrams to Google Docs
Google Docs cannot render Mermaid code, and unlike Word it does not accept SVG images either. The dependable workflow is a high-resolution PNG: render the Mermaid diagram in your browser, export a 2x PNG, and insert it through Insert → Image. No add-ons, no Workspace admin approval, no upload of your diagram source.

Does Google Docs render Mermaid natively?
Google Docs has no built-in Mermaid rendering. Third-party Mermaid add-ons exist in the Workspace Marketplace, but they require installation — often blocked by Workspace admins — and they render inside the add-on sidebar rather than your document flow. Since Google Docs also rejects SVG uploads, a high-resolution PNG is the format that simply works for everyone, including viewers and commenters.
Insert a Mermaid diagram into Google Docs
- 1
Paste your Mermaid code
Drop your flowchart or sequence diagram code into the converter below. It renders locally in your browser — nothing is sent to a server or add-on.
- 2
Keep the style document-friendly
Clean Docs on a white background reads like a native figure inside a Google Doc. Avoid transparent backgrounds here: Docs pages are always white anyway.
- 3
Export a PNG at 2x
Google Docs does not accept SVG, so PNG is the format of choice. The 2x scale keeps labels sharp on retina screens and in the PDF the doc will eventually become.
- 4
Insert via Image upload
In Google Docs choose Insert → Image → Upload from computer and select the PNG, or drag the file straight into the document. Use the image options to set wrapping and alignment.
Export your diagram here
Paste your Mermaid code below, pick a style, and download the image. Everything renders locally in your browser — no signup, no watermark.
Export controls activate after your diagram renders locally.
Which format works best in Google Docs?
Google Docs rejects SVG uploads, and JPG softens diagram lines. A 2x PNG is sharp, compatible, and looks right in print and PDF downloads.
Add-ons need per-user installation and are often blocked in company Workspaces. An image works for every collaborator with zero setup.
Keep the Mermaid code in your repo, wiki, or a comment near the figure. To update the diagram, re-export the PNG and use Replace image in Docs.
FAQ
Questions about this workflow
Can Google Docs render Mermaid code directly?+
No. Google Docs has no built-in Mermaid support. Convert the diagram to a PNG image in your browser and insert it with Insert → Image → Upload from computer.
Why can't I insert an SVG into Google Docs?+
Google Docs does not support SVG uploads at all — the insert simply fails or the file is rejected. Export a 2x or 4x PNG instead; it is the highest-fidelity format Docs accepts.
Do Mermaid add-ons for Google Docs work?+
Marketplace add-ons exist, but each collaborator must install them, many company Workspaces block third-party add-ons, and rendering happens in a sidebar. A plain PNG insert avoids all of that.
How do I update the diagram after the doc is shared?+
Right-click the image in Google Docs and choose Replace image, then upload the freshly exported PNG. Comments and positioning on the figure are preserved.
