Free online MM to DOT converter

Source format: MM

MM files are typically FreeMind mind map documents. They store a hierarchical outline of ideas, tasks, and notes in an XML-based structure. These files are commonly used by students, project managers, writers, and teams who need to organize information visually in mind maps. Typical use cases include brainstorming, planning, note-taking, and structuring complex topics.

Target format: DOT

DOT is a Graphviz graph description format used to define nodes and edges in a graph. It is widely used by developers, data analysts, and technical writers to generate diagrams such as dependency graphs, flowcharts, network maps, and decision trees. Its main advantages are plain-text readability, strong support in Graphviz tools, and easy integration into automated workflows.

How to perform the conversion

There is no universal one-click conversion from MM to DOT because the formats represent information differently: a mind map is a tree-like outline, while DOT is a general graph language. The best approach is usually to export or transform the mind map structure into a graph description.

1. Open the MM file in a mind map editor such as FreeMind or Freeplane.
2. Inspect the structure and decide how you want the map represented in Graphviz: as a tree, a directed graph, or a more complex network.
3. Export or convert the content using a script or tool that can read the XML inside the MM file and generate DOT syntax. If you are comfortable with scripting, this is often the most accurate method.
4. Save the result as filename.dot.
5. Render or validate the DOT file with Graphviz if needed, for example, by running dot -Tpng filename.dot -o filename.png.

If you only need a quick online conversion, you can try to convert the file on 101convert.com for free, without installing any software.

For manual conversion, a simple DOT tree might look like this: digraph G { "Root" -> "Child 1"; "Root" -> "Child 2"; }

Notes on quality, compatibility, or limitations

MM to DOT is not a perfect format match. MM mind maps preserve layout, icons, colors, notes, and rich formatting, while DOT mainly captures relationships between nodes. As a result, visual styling and some metadata may be lost unless you explicitly encode them in DOT attributes.

Compatibility also depends on the source file version. Most MM files are XML-based and can be parsed reliably, but very large or heavily customized mind maps may require a dedicated converter or custom script. If your goal is only to visualize the hierarchy, DOT works well. If you need to preserve the original mind map's appearance, consider exporting it as an image or PDF instead.
