What is MKV and MP4?
MKV is a Matroska Multimedia Container format that can hold an unlimited number of video, audio, picture or subtitle tracks inside a single file. It is intended to serve as a universal format for storing common multimedia content, like movies or TV shows. MKV can hold all of the same digital elements of MP4. MKV can also compress high quality videos into smaller files.
MPEG-4 Part 14 or MP4 is a digital multimedia container format most commonly used to store video and audio, but it can also be used to store other data such as subtitles and still images. Like most modern container formats, it allows streaming over the Internet.
Why Convert MKV to MP4?

In addition, even if you can play MKV files on some software-based media players like VLC, but you may fail to load them into the default media player apps on Windows such as Windows Media Player or household media players like iTunes. To fix this problem, it would be much idea for you to convert MKV to MP4, a more program or device compatible file format for viewing anywhere at any time.
