About MJ files
The .MJ file extension is primarily associated with AI-generated images created by Midjourney. Alternatively, it serves as a proprietary video container for DVR surveillance systems manufactured by Xiongmai Technology. Both formats present significant usability challenges. The DVR video variant is heavily restricted, lacking native support in web browsers or standard media players like VLC. Sharing these raw files with law enforcement or clients is a major hassle because they require obscure playback software. Converting .MJ images to JPG ensures universal compatibility, while converting surveillance videos to MP4 is critical for playback. The DVR variant of the .MJ format is notoriously difficult to open or convert due to non-standard encoding. Often, only the original hardware or software can properly read or export the data. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your MJ file, detects the exact format, and lets you read the text inside.
Users also converted CPK, SNX, THP, MW and J files.

The MJ 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 MJ converter.
