The reason why we need to convert MKV into another file container format like MP4 is that many programs don't support the playback of MKV files. MKV files cannot be successfully open on a variety of devices. As a wide-range compatible file container format, I would say, the MP4 coordinates much better with various programs than the MKV. It is a good news that to convert MKV to MP4 is not complicated at all, and nowadays most video converters can achieve the conversion between MKV and MP4.

What is MKV File?
MKV is also known as a Matroska Multimedia Container format that holds unlimited video, audio, picture and subtitle tracks all in one file. It is a completely open sourced file format similar to MP4. Compared with MP4 file format, it is less compatible and has a lower popularity amongst the media containers. It is based on Extensible Binary Meta Language and supports several videos as well as audio compression formats. One character of the MKV to distinguish it from other video extensions is that it is a container rather than a codec.
There are different file extensions that are associated with the MKV format, namely MKV for video, mka for audio and mks for subtitles.
As far as the compatibility of the MKV is concerned, you might find many systems that do not support the playback of files with MKV extension or container format. Therefore, it is necessary to convert MKV into another file format, such as MP4.

But I would call the method of using a video converter as the most straightforward way as it doesn't involve with any technical operation such as using the command line in the solution of FFmpeg. And as another question, since solutions of converting MKV to MP4 differ with each other, will it make any difference in maintaining the quality of the original video if you use different conversion methods.
Will I Lose Quality After VLC Convert MKV to MP4?
Whether the conversion of the MKV file causes lose in its quality depends on what solution you are using to convert. There are both lossy and lossless ways of converting an MKV file into MP4 format. Let's talk about this more specifically.
We like all the files to be lossless within a conversion process. However, being lossless sometimes means that you couldn't do anything about it, including changing the video quality or the video resolution. Therefore, we need to compromise the quality of the original file to create a new file.
For lossless conversion, you are only transferring the video from MKV container format to MP4 format, or duplicate the original file with the same quality. There is no modification on the video. It can be achieved by using the solution of command line such as FFmpeg. Nothing will be changed in rewriting the command line.
For lossy conversion, in most of the cases, you want to change the video quality or the video resolution so that you can get a new video with an optimized effect. The software you are using for conversion will re-code the video. It is generally defined as lossy conversion, which can be achieved by using Handbrake and VLC media player.
The concept of converting a file in a lossless or lossy way can also apply to other types of conversion such as converting M4V to MP4, WMV to AVI. As long as the quality or the video resolution is modified, it generates a lossy file.
