Free online EMMX to ITMZ converter

EdrawMind saves editable mind maps as EMMX, while iThoughts uses ITMZ, so conversion is needed when a map must be opened or continued in iThoughts. The most reliable desktop route is to export the EMMX map through an interchange format that iThoughts can import, then save it as ITMZ.

What the EMMX format is

EMMX is the native project format of EdrawMind. It stores a mind map's hierarchy, topics, relationships, formatting, notes, boundaries, markers, attachments, and other EdrawMind-specific data. You encounter it when a map is created or saved in EdrawMind on desktop or through its compatible project workflow.

What the ITMZ format is

ITMZ is the native compressed mind-map format used by iThoughts and iThoughtsX. It is intended for editable maps rather than final-view documents, and it preserves the structure needed to continue editing topics, branches, notes, links, and map styling in iThoughts.

How to convert EMMX to ITMZ

Using EdrawMind and iThoughts

1. Open the .emmx file in EdrawMind.
2. Choose File → Export and select an interchange format supported by your iThoughts version. OPML is usually the safest choice for preserving the map hierarchy; FreeMind or MindManager format may retain more map-specific structure when both applications support it.
3. Save the exported file and open it in iThoughts or iThoughtsX with File → Import.
4. Check the imported branches, notes, hyperlinks, labels, and attachments. Correct any missing or rearranged content.
5. Save the imported map with File → Save As and choose the iThoughts format, producing an .itmz file.

Using the online converter

You can convert the file on the 101convert.com website for free without installing software. Upload the .emmx file, choose ITMZ as the output format if it is offered, start the conversion, and download the resulting file. Open the result in iThoughts to verify that the map is editable and complete.

Compatibility and limitations

There is no universal interchange specification for every EdrawMind and iThoughts feature. OPML normally transfers the outline and topic text but can discard canvas positioning, themes, boundaries, summaries, images, attachments, task fields, and application-specific metadata. Exporting through FreeMind or MindManager can preserve more visual information, but the result still depends on the versions and import capabilities of both applications.

Keep the original EMMX file as a backup, especially when the map contains embedded files or complex cross-links. After conversion, inspect collapsed branches, relationship lines, icons, notes, and external links before deleting the source.
