About SMMX files
An .SMMX file is a proprietary mind map document created by SimpleMind, primarily used for brainstorming, project planning, and visual organization. You can natively open and edit these files using SimpleMind Pro across macOS, Windows, iOS, and Android. However, because the format is locked to this specific ecosystem, users without the software will be completely unable to open the .SMMX file on a standard PC or mobile device. Sharing these files with clients or colleagues forces them to download a dedicated viewer. To make your mind maps accessible, converting the file to standard formats is highly recommended. For preserving the exact visual layout, converting to PDF or PNG is ideal. If you need to transfer the text structure to other outlining tools, converting to OPML, MM (FreeMind), or TXT works best, though doing so will permanently strip away custom icons, cross-links, and embedded media. Because .SMMX is a highly specific, proprietary file format, standard online converters usually fail to process it. Often, only the original software can properly read or export the visual data. Just drag and drop your file to convert.guru to see what it is and convert it if supported. We can identify the file format, inspect the underlying ZIP container, and show text or internal content. If our analysis detects a supported embedded format, viewing or extracting the assets may still be possible.
Convert.Guru analyzes your SMMX file, detects the exact format, and lets you read the text inside.
Users also converted SM2STORE, SMX, BTW, MMAP, EMMX and MMP files.

The SMMX Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our SMMX converter.
