Free online ITMZ to PNG converter

What the ITMZ format is

ITMZ is the native mind-map document format used by iThoughts and related iThoughts applications, including iThoughtsX on macOS. It stores the editable map structure: topics, branches, notes, relationships, icons, formatting, and other map data. You typically encounter it when someone sends an iThoughts map or when a map is exported from iThoughts on a computer or mobile device.

ITMZ is intended for continued editing in compatible iThoughts software, not for direct viewing in standard image applications. Renaming .itmz to .png does not convert the file.

What the PNG format is

PNG is a raster image format supported by web browsers, office software, graphics editors, operating systems, and most document-management systems. It uses lossless compression, so text and line graphics remain sharper than they would in a similarly sized JPEG file.

PNG is suitable for sharing a finished mind map, embedding it in a report or slide, printing at a selected resolution, or archiving a view that does not need further structural editing. It does not preserve editable branches, notes, hyperlinks, collapsible topics, or the original map layout as separate objects.

How to actually convert ITMZ to PNG

Using iThoughts or iThoughtsX

1. Make a backup of the original .itmz file.
2. Open the file in the compatible iThoughts application.
3. Adjust the map before exporting: expand any branches that must appear, set the desired central topic and orientation, and hide panels or selections that should not be included.
4. Open File → Export or the application’s Share/Export command, then choose Image, PNG, or the equivalent image-export option.
5. Set the page or canvas size, scale, background, and transparent-background option if available. Choose a higher scale or resolution for maps containing small text.
6. Select an output folder, confirm the .png filename, and export.

Menu names vary between iThoughts versions and platforms. If PNG is offered directly in the image-export dialog, use it rather than taking a screenshot; direct export usually preserves more detail and includes the complete map canvas.

Using the online converter

You can convert the file on 101convert.com for free without installing software. Upload the ITMZ file, select PNG as the output format, start the conversion, and download the resulting image. Use the desktop application instead for confidential maps or when you need control over canvas size, scaling, transparency, and which branches are visible.

Quality and compatibility limitations

• PNG is a single flattened image. The resulting file cannot be reopened as an editable iThoughts map.
• Very large maps may produce a wide or tall image with unreadably small text. Export separate branch images or increase the output scale when the application supports it.
• Collapsed branches, hidden topics, off-canvas objects, and filtered content may not appear in the PNG. Expand and review the map before exporting.
• Fonts and icons can change if the source application lacks the original resources; check the exported image for substituted fonts, missing symbols, and clipped labels.
• Keep the ITMZ file as the master copy. PNG preserves visual appearance but not notes, attachments, links, relationships, or map hierarchy as editable data.
