How to Convert MKV to MP4 on Windows


MKV is a multimedia container format that often stores multiple audio and subtitle tracks. However, since it is not as popular as other video file formats, such as MOV and MP4, playing MKV file may become difficult on Windows computer.

If your device does not support MKV format, you can convert it to MP4. It is a common multimedia format supported by almost all devices. Here we show you the best online and offline tools to convert MKV to MP4 on Windows.

VLC is a free and open-source media player that supports almost all audio and video formats including MKV. If you have VLC installed, you don’t need to convert and play the video. However, if you still need to convert your MKV video, you can do so using VLC’s Convert feature. This is one of the best hidden features of VLC media player.

To convert MKV file to MP4 using VLC media player, follow these steps:

  1. Open the VLC Media Player app on your PC.

The VLC media player timeline will show the conversion progress. When done, it will save your video to the destination folder.

Although VLC media player provides a convenient way to convert videos, sometimes the output file may lose audio during the process. You can solve this problem by using a dedicated video converter.
