Users often get confused when they download a free video, but their player can’t open it. It happens mostly because some file extensions like MKV are incompatible with many media players and web services. Free AVS Video Converter solves the problem easily converting your MKV files into more popular formats like MP4 without losing quality.
MKV and MP4 in comparison
MKV and MP4 are high-quality container formats and hold videos, audios, images and subtitles. They are both suitable for online streaming. Still, they are different and, hence, have strong and weak points when it comes to some particular purposes. Let us take a closer look at each of the two.

To sum it up, the two compared formats have their pros and cons. It would be wrong to say that one is better than the other, but it is clear that each of them meets users’ individual needs.
MKV is a feature-rich format that can hold an unlimited number of content types. It has a perfect resolution and a free license, supports almost all video and audio coding formats. However, MKV is really bulky as compared to other formats. Besides, you need a special software compatible with Matroska to play it.
MP4 is one of the most universal multimedia formats today. It is supported by all kinds of media players, devices, operating systems and video platforms. MP4 is a good choice if you need a video of smaller size to open it on a mobile device or some web service.
