Free online XMIND to MM converter

A map created in XMind may need conversion when the recipient uses FreeMind or Freeplane, which open the MM format, or when an application requires plain XML instead of an XMind package. The conversion creates a compatibility copy for editing or sharing while the original remains available for archival use.

What the XMIND format is

.xmind is the native file format used by XMind for mind maps, outlines, brainstorming diagrams, and related visual structures. An XMind file is normally a ZIP-based package containing map data, styles, metadata, and possibly images or other attachments; its internal files and data representation vary by XMind release. Older XMind releases may also use .xmap.

XMind is used by individuals, teams, educators, and project groups to organize hierarchical ideas and information. Its package format can preserve features that a simpler interchange format cannot.

What the MM format is

.mm is the FreeMind XML mind-map format. Freeplane and some other mind-mapping programs can open it. An MM file stores a hierarchical node tree with node text, links, notes, folding state, icons, and selected formatting attributes.

Because MM is plain-text XML, it can be inspected, edited, and version-controlled with standard tools. It is useful when a map must be opened in FreeMind or Freeplane, processed by XML-aware software, or retained in a simple format that is less dependent on XMind-specific packaging.

How to convert the file

Using 101convert

1. Open the built-in XMind-to-MM converter on 101convert.com.
2. Select or drop the source .xmind file.
3. Choose MM as the output format and start the conversion.
4. Download the resulting .mm file.
5. Open it in FreeMind or Freeplane and verify the hierarchy, text, links, notes, and special characters.

This option runs without installing desktop software and is available free on 101convert.com. Upload maps only when their contents are permitted to leave your computer; use a local application for confidential material.

Using XMind desktop

Some XMind desktop releases can export directly to FreeMind XML. Open the map and choose File → Export, then select FreeMind or FreeMind Map. Save the output with the .mm extension, then open it with FreeMind → File → Open or Freeplane → File → Open. Menu names and export options differ between XMind versions, so the direct method is unavailable in some releases.

If the XMind installation has no FreeMind export, use the converter instead of renaming the file. Changing .xmind to .mm changes only the filename extension and leaves the incompatible package structure unchanged.

Compatibility limitations

MM describes a simpler model than XMind. The central topic, child-node hierarchy, basic text, hyperlinks, notes, and some icons usually transfer. XMind themes, sheet-level styling, boundaries, relationships, summaries, labels, markers, task data, attachments, and embedded media may be omitted or simplified.

XMind workbooks can contain multiple sheets. Depending on the XMind version or conversion tool, sheets may become separate MM files, only the active sheet may be exported, or sheet-specific features may be flattened. Check every required sheet and any cross-sheet links after conversion.

Keep the original .xmind file as the full-fidelity copy. Treat .mm as an interoperability copy, and save it from FreeMind or Freeplane after checking node order, links, notes, encoding, and formatting.
