MJPG File Extension

Have a problem opening a .MJPG file? We collect information about file formats and can explain what MJPG files are. Additionally we recommend software suitable for opening or converting such files.

What is the .MJPG file type?

The .mjpg file extension is associated with Motion JPEG, or M-JPEG video files. They represent a sequence of frames encoded with the JPEG algorithm. When combined, the frames provide the illusion of watching a motion video. MJPG files are usually created by digital cameras, mobile phones and other digital devices.

M-JPEG files are compressed using an intraframe compression technique. It is considered to be less efficient in comparison with the interframe compression. That’s why .mjpg files require more bandwidth and storage space than their MPEG competitors.

On the other hand, the M-JPEG video decompression process takes less time and any frame can be referenced independently. It means that if one of the frames gets corrupted, it is still possible to play back the video.

M-JPEG files may come wrapped in AVI (on Windows) or QuickTime (on Mac) container files. If your player doesn’t support the .mjpg file format natively, there are many video conversion tools that can turn your .mjpg files into more common video formats.
