Convert MGV files online for free
The converter easily converts your MGV file to various formats - free and online. No Media Player or extra software needed.
The converter also works in reverse, so you can convert other Video formats to MGV with high quality output.
A .mgv file is most commonly a proprietary video file associated with the Sony PlayStation Portable (PSP) or specific Digital Video Recorders (DVR) like the MultiGo dashcam.
Historically, these files were stored on the PSP's Memory Stick Duo under strict directory structures (e.g., /MP_ROOT/100MNV01/). While technically based on the MPEG-4 or H.264 standards, the .mgv extension acts as a "wrapper" that prevents standard media players from recognizing the content. Users often encounter these when recovering old backups from the mid-2000s.
Less frequently, an .mgv file is a raw video stream from a MultiGo car dashcam or security DVR. These devices use the extension to enforce proprietary playback via their specific software, often locking the file preventing easy sharing or editing.
In a music production context, this file is a MegaVoice definition used by Yamaha keyboards (like the Tyros or PSR series). These are not audio files but proprietary data instructions that tell the synthesizer how to articulate sounds (e.g., guitar slides, fret noise).

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 MGV converter.
