Extract text from game videos and faxes (MMR)
To convert MMR videos and faxes to another format, you need Princess Connect! Re:Dive or other Video software.
To convert other file formats to the "Renamed MPEG-4 Container" file type, you need software like Princess Connect! Re:Dive or a similar tool.
The .mmr extension creates confusion because it serves two completely unrelated purposes in the digital ecosystem.
1. Princess Connect! Re:Dive Video (Most Common):
For most modern users, an MMR file is actually a standard MPEG-4 video file that has been renamed by the Princess Connect! Re:Dive mobile game to obscure its contents. These files contain cutscenes, skill animations, or background movies. The "friction" here is artificial; the file is technically sound, but the extension prevents standard players like VLC or Windows Media Player from recognizing it. Users typically convert these to MP4 or MKV to watch game assets outside the app or for video editing.
2. Fuji Xerox Fax Image (Legacy):
Historically, MMR stands for Modified Modified Read, a specific compression algorithm used by Fuji Xerox (now Fujifilm Business Innovation) for storing fax documents. Unlike the game video, this is a legitimate proprietary raster image format. It is highly compressed for telephone transmission, making it incompatible with modern web browsers and image viewers. To view or archive these documents, they must be converted to PDF or TIFF.
3. Audio Recordings:
Rarely, this file may be a recording from Minutes of Meeting Recorder software. These are proprietary audio containers that often require conversion to MP3 for playback on standard devices.
Convert.Guru analyzes your MMR file, detects the exact format, and lets you read the text inside.

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 MMR converter.
