Free online ITMZ to SVG converter

People convert ITMZ maps to SVG when they need to place a mind map in a web page, document, diagram editor, or scalable print layout. SVG preserves vector rendering at different sizes, while ITMZ is mainly intended for editing inside iThoughts.

What the ITMZ format is

ITMZ is the native compressed mind-map format used by iThoughts and iThoughtsX. It stores a map's branches, labels, colors, layout, notes, links, icons, and other editing information in a package based on structured XML. You encounter ITMZ files when maps are created or saved in iThoughts on supported desktop or mobile devices.

An ITMZ file is not an image, so changing its extension or unzipping its contents does not produce a usable SVG. The map must be opened by software that can interpret its structure and render the layout.

What the SVG format is

SVG is an XML-based vector graphics format supported by web browsers, office applications, illustration software, and many publishing workflows. A mind map exported as SVG can be enlarged without pixelation, edited as graphic artwork, embedded in HTML, or sent to a vector-capable print workflow.

SVG is suitable for the map's visual presentation rather than continued mind-map authoring. It does not generally retain ITMZ's branches as application-native nodes, notes, task data, or map metadata.

How to convert ITMZ to SVG

Using iThoughts or iThoughtsX

1. Open the .itmz file in iThoughts or iThoughtsX.
2. Check the map's page size, orientation, branch visibility, text wrapping, and zoom before exporting. Expand or collapse branches as needed for the intended graphic.
3. Choose File → Export or the application's equivalent export command, then select SVG.
4. Choose the destination and save the resulting .svg file.
5. Open the SVG in a browser or vector editor such as Inkscape to check clipping, text placement, colors, and connector lines.

The exact menu labels vary by iThoughts version and operating system. If SVG is not listed, update the application or use its PDF export and convert the PDF to SVG in a vector editor; that fallback can alter text and effects, so inspect the result carefully.

Using the online converter

You can convert the file for free on the 101convert.com website without installing software: upload the ITMZ file, select SVG as the output format, start the conversion, and download the generated file. Use the desktop application instead when the map contains confidential information or when export settings must be controlled precisely.

Quality and compatibility limitations

The SVG contains a rendered diagram, not a fully editable ITMZ data model. Reopening it in a mind-map application may not restore hierarchy, notes, hyperlinks, task fields, or automatic layout. Keep the original ITMZ file as the editable source.

SVG appearance can change when the recipient lacks the fonts used by the map. For reliable sharing, embed fonts where the export software supports it, convert text to outlines in a vector editor when editing text is unnecessary, or verify the file in the target browser or design application. Large maps may produce very large SVG files, and unsupported shadows, icons, hyperlinks, or embedded images may be simplified or omitted.
