How to Insert Mermaid Diagrams in Google Docs

Google Docs has no built-in Mermaid support, so pasting diagram code into a document shows plain text. The reliable workflow is to render the code in your browser, export it as a PNG image, and insert that image into the Doc. It needs no add-on, no account permissions, and nothing installed — and because the rendering happens locally, the diagram code for internal specs never leaves your machine.

Does Google Docs render Mermaid natively?

No — insert an image

Google Docs does not render Mermaid syntax on its own. Google Workspace Marketplace add-ons for Mermaid exist — including one from Mermaid Chart Inc. and community toolkits — but every add-on needs to be installed and granted permissions on your Google account, and some IT teams lock marketplace installs down. Inserting an exported image bypasses all of that: it works in every Docs account, including managed school and work accounts.

Insert a Mermaid diagram into a Google Doc

  1. 1

    Paste your Mermaid code

    Drop your diagram code into the converter below. It renders locally in your browser — nothing is uploaded, which matters for draft specs and internal documentation.

  2. 2

    Keep it document-friendly

    Google Docs pages are white, so use the white background with the Clean Docs style: the diagram reads like a native figure rather than a pasted screenshot. Keep backgrounds white so the image blends into the page.

  3. 3

    Export PNG at 2x

    Docs keeps the resolution you upload, so a 2x PNG stays sharp when the Doc is printed or downloaded as PDF. A 1x screenshot is what makes diagrams look soft on paper.

  4. 4

    Insert into the Doc

    Use Insert → Image → Upload from computer, or drag the file straight into the document. Docs wraps the image as an inline figure by default; use the image options to center it or wrap text around it, and add alt text for accessibility.

Which export works best in Google Docs?

PNG at 2x — the default

Displays reliably in every Docs account and every export path: PDF download, print, and mobile apps. 2x scale keeps labels readable on paper.

PNG at 4x — for print-heavy docs

If the document will be printed or exported to PDF at full size, 4x gives labels extra headroom. File size stays modest for typical diagrams.

Why not SVG here

Google Docs cannot edit SVG files and its handling of them varies by account and export path, so a crisp 2x or 4x PNG is the dependable choice for documents.

FAQ

Questions about this workflow

Can Google Docs render Mermaid code directly?+

No. Docs has no built-in Mermaid engine. Convert the diagram to a PNG image and insert it like any other figure.

Is there a Mermaid add-on for Google Docs?+

Yes — the Workspace Marketplace lists a Mermaid for Google Docs add-on from Mermaid Chart Inc. plus community toolkits. They require installing an add-on and granting it permissions on your Google account, and the Mermaid Chart one is built around their paid service. For a figure in a document you need none of that: export an image and insert it.

How do I insert a Mermaid diagram in Google Docs without an add-on?+

Paste your code into the converter on this page, export a 2x PNG, then use Insert → Image → Upload from computer in your Doc. That is the entire workflow — no installation, no account permissions.

How do I render Mermaid code in Google Docs?+

Google Docs will not render the code itself, so render it outside the document: this page converts Mermaid code to an image locally in your browser, and you insert the exported PNG into the Doc.

Does the image stay sharp when the Doc is shared or printed?+

Yes, if you export at 2x or higher. Docs keeps the resolution you upload; 1x screenshots are what look soft in printed and PDF-exported documents.

Can collaborators edit the diagram?+

Not the image — Docs treats it as a picture. Keep the Mermaid code in the Doc (in a code block or comment) or paste this editor's Share link, which carries the whole diagram. Anyone can reopen it, change the code, and re-export.

PNG or SVG for Google Docs?+

PNG. Docs cannot edit SVG files and how it handles them varies by account, while a 2x or 4x PNG displays reliably everywhere — web, mobile apps, PDF export, and print.

Is my diagram code uploaded anywhere?+

No. This converter renders Mermaid locally in your browser, so draft specs and internal diagrams never leave your machine.
