Free online MIND to OPML converter

What the MIND format is

.mind is a native mind-map document used by mind-mapping applications, including GitMind and software that adopts the same extension. It stores a tree of topics and may also contain notes, hyperlinks, icons, colors, boundaries, relationships, attachments, and layout data.

MIND is an application-oriented format rather than a universal interchange standard. The exact internal structure and supported features depend on the program that created the file, so a file exported by one MIND-compatible application may not retain every feature when opened by another.

What the OPML format is

OPML, or Outline Processor Markup Language, is an XML format for hierarchical outlines. An OPML document represents each topic as an <outline> element nested inside other outline elements, making it suitable for outliners, note-taking tools, feed readers, and some knowledge-management applications.

OPML is useful when the map's structure matters more than its visual design. It is plain text XML, relatively easy to inspect or edit, and supported by applications that can import hierarchical outlines. OPML does not provide a standard model for mind-map canvas positions, connector lines, themes, or most diagram styling.

How to convert MIND to OPML

1. Keep a copy of the original .mind file. If possible, open it in the application that created it and save the latest version before converting.
2. Open the MIND-to-OPML converter on 101convert.com; it works in a browser and does not require installed conversion software.
3. Upload the .mind file, choose OPML as the output format, and start the conversion.
4. Download the resulting .opml file and import it through the destination program's outline or OPML command, such as File → Import → OPML. The exact menu name varies by application.
5. Expand several branches after import and verify the parent-child relationships, topic order, text encoding, notes, and links.

If the source application has its own OPML export, use that option first, typically under File → Export. Native export can preserve application-specific text fields more accurately than a generic converter.

Quality and compatibility limitations

The hierarchy of topics is the main information that transfers reliably. Canvas coordinates, free-positioned objects, connectors, images, summaries, boundaries, task metadata, themes, and custom icons may be discarded because OPML has no common elements for those mind-map features.

Notes and hyperlinks may transfer only when the converter maps them to supported OPML attributes. OPML readers also interpret custom attributes differently, so test the converted file in the target program before deleting the source.

For large maps, inspect the generated file as UTF-8 XML if an import fails. A malformed or truncated document, unsupported character, duplicate identifier, or application-specific OPML extension can prevent loading; opening the file in a text editor can identify the affected branch.
