Mermaid to Drawio Converter

Paste code, and the Mermaid to Drawio conversion builds native shapes and connectors. Adjust the result in the embedded diagrams.net editor, then download a .drawio file, PNG, or SVG. No account or credits are required.

From Diagram Code to a Diagram You Can Arrange

Mermaid is excellent for keeping diagrams beside code and documentation, but its rendered output is hard to rearrange by hand. A Mermaid to Drawio conversion keeps the structure you wrote and gives you individual shapes, labels, and connectors that respond to normal Draw.io editing.

Native Shapes, Not a Picture

A Mermaid to Drawio conversion turns each node into its own shape and each link into a connector. You can move a box, rename a step, or change a color without rewriting the source.

Common Mermaid Diagram Types

Flowcharts, sequence diagrams, class diagrams, entity relationship diagrams, state diagrams, and mind maps are included as examples. Several other Mermaid types are understood as well.

Files for the Next Step

Keep working in Draw.io with a .drawio file, publish a PNG, or place a scalable SVG in documentation. The same edited canvas produces every download.

Three Steps

How to Convert Mermaid to Draw.io

The whole Mermaid to Drawio process takes about a minute and happens on this page.

Paste Mermaid Code

Paste a diagram into the code box or start from one of the examples. Markdown fences are optional, and the character counter shows how close you are to the limit.

Convert and Adjust

Select the convert button. The Mermaid to Drawio result opens in the embedded editor, where you can move shapes, edit text, and change styles before saving.

Download or Copy

Save a .drawio file to keep editing later, export PNG or SVG for publishing, or copy the Draw.io XML to paste into another diagram.

How to Get a Clean Draw.io Diagram From Mermaid

Good source code, sensible expectations about layout, and the right output format all affect the result.

Why Teams Move Mermaid Diagrams Into Draw.io

Mermaid works well while a diagram lives next to the code it describes. Problems start when the diagram has to appear in a slide deck, a design review, or a document edited by people who do not write code. A Mermaid to Drawio conversion hands those readers a diagram they can change with a mouse.

Draw.io also offers controls that text cannot express precisely: exact positions, custom colors per shape, icons from large shape libraries, and multiple pages. Converting once lets you keep Mermaid as the quick draft and Draw.io as the polished, presentation-ready version.

What the Converter Keeps and What It Recalculates

Node labels, node shapes such as rectangles, rounded steps, and decisions, link labels, and the direction of each connection are carried into Draw.io. Subgraphs become grouped areas, and class or entity attributes stay inside their boxes.

Layout is recalculated by the Draw.io engine, so spacing can differ from the picture Mermaid draws in a browser. Treat the first Mermaid to Drawio result as a well-structured starting point. A few drags usually produce a tidier diagram than either tool creates automatically.

Prepare Code That Converts Reliably

Begin the text with a declared diagram type such as flowchart TD, sequenceDiagram, or erDiagram. Give nodes short IDs and readable labels, and quote labels that contain punctuation. Code that renders correctly in the Mermaid live editor is the best predictor of a successful Mermaid to Drawio result.

Very large diagrams are easier to edit when split into several smaller ones. The page accepts up to 50,000 characters, but a diagram with hundreds of nodes becomes crowded on any canvas. Convert each section, then combine pages in Draw.io if needed.

Choose the Right Download Format

After a Mermaid to Drawio conversion, download the .drawio file whenever the diagram will change again. It opens in diagrams.net, the Draw.io desktop app, and the Draw.io integrations for Confluence, Jira, Google Drive, and VS Code, with every shape still editable.

Use PNG for chat, tickets, and email, where a simple image is expected. Choose SVG for documentation sites and print, because it scales without blurring. The Copy XML button places the diagram on your clipboard for pasting into an existing Draw.io file through Extras, Edit Diagram.

A Practical Bridge Between Mermaid and Draw.io

This Mermaid to Drawio tool focuses on the steps people usually take right after the code renders.

Conversion by the Draw.io Editor Itself

The embedded diagrams.net editor parses the Mermaid text and creates the cells. This is the same engine that opens your diagram later, so styles and connectors behave as they normally would.

Edit Before You Export

Adjust spacing, align a lane, shorten a label, or add a note directly on the canvas. Every download reflects the edited diagram rather than the original layout.

Paste From a README

Text copied with a Markdown code fence is accepted. The fence is removed before conversion, so a Mermaid to Drawio conversion works on a block taken from a repository wiki or pull request without cleanup.

Clear Errors for Unsupported Code

When the parser cannot read the text, the page shows the reason, such as an unknown diagram type. Fix the line and convert again instead of guessing what went wrong.

Draw.io, PNG, and SVG Downloads

Every Mermaid to Drawio result can be saved as an editable .drawio file, a 2x PNG on a white background, or an SVG that stays sharp at any size.

No Account and No Credits

This page does not create a conversion record or use credits. The code stays in your browser, and nothing is stored in your ImageToDrawio account.

FAQ

Mermaid to Draw.io Questions

Answers about supported code, layout, privacy, and output files.

Which Mermaid diagram types are supported?

Flowcharts, sequence, class, entity relationship, state, mind map, Gantt, and pie diagrams convert into native shapes. Other types may also work. If a type is not recognized, the page shows an error instead of an empty canvas.

Is the Mermaid to Drawio output editable?

Yes. Nodes become separate shapes and links become connectors, so you can select, move, restyle, and relabel them. The result is a real Draw.io diagram, not a flat image placed on the canvas.

Why does the layout look different from Mermaid?

Draw.io calculates its own layout for the converted cells. The structure and labels match your code, but spacing and routing can differ. Drag shapes or use the Arrange menu to tidy the diagram.

Can I do this inside Draw.io?

Draw.io can insert Mermaid from its Insert menu under Advanced. This page is useful when you want a quick Mermaid to Drawio conversion without opening a file, along with ready PNG and SVG downloads.

Is my code uploaded anywhere?

The conversion runs in the diagrams.net editor embedded in this page. Your code is not posted to the ImageToDrawio conversion API, and no record is saved to an account.

Can I convert a Mermaid diagram to an image?

Yes. After converting, choose PNG for a raster image or SVG for a vector image. Both are created from the current canvas, so any edits you make appear in the image.

Is there a size limit?

The code box accepts up to 50,000 characters. Large diagrams may still be slow to edit or hard to read, so splitting a complex system into a few focused diagrams usually works better.

What if I only have a picture of the diagram?

Use the image to Draw.io converter instead. It reads a screenshot or photo with AI and rebuilds the shapes and text as an editable Draw.io diagram.

Paste the code, review the converted shapes, make the adjustments that text cannot express, and download the format you need.
