Have you downloaded a video in MKV format and it takes up so much space that you don’t know what to do with it? Don’t worry, you are not the only one. Although Mastroska files offer a picture quality comparable to that of a Blu-Ray, it takes up a lot of space on your hard drive and is not always compatible with video players. That is why it is common to convert MKV videos to AVI, MP4 or any other lighter format for easy viewing, storing and sharing. But how to do it?

In today’s article we are going to show you how to convert MKV video quickly and easily. There are countless free programs that you can use to convert this video format in just a few seconds. All of them will be really useful if, for example, you need to reduce the size of your MKV files or if, for example, you want to watch a video on your Smart TV and it is unable to play this file format. We hope they will help you!

What is an MKV file and what is it used for?

The MKV format, also known as Matroska Video, is a file type capable of storing several videos, audio tracks and subtitles within the same file. It is really versatile, because unlike others, it is not an audio or video compression format, but a multimedia container. Thus, in the same MKV file we could find, for example, a video in H.264 format and an audio in MP3 that would be played simultaneously by double-clicking on it.

The MKV format is especially popular when digitizing a DVD or Blu-Ray. It is capable of adding an unlimited number of multimedia files of different formats within the same file, preserving their quality and with the ability to add DVD-style menus. In fact, an MKV file even allows quick searches within the same file. That is why they are usually large files compared to, for example, MP3 or AVI files.

Why convert an MKV file to another format?

As mentioned in the previous point, MKV files are very versatile and especially useful for digitizing DVDs or Blu-Rays. They can contain an unlimited amount of videos, audios and subtitles in a single file without losing any quality. However, it is very common after downloading or creating an MKV file to convert it to a lighter format.

Here are the main reasons for converting an MKV file:

  • To reduce its size– Since an MKV file is not an audio or video compression, but a multimedia container, its files can have gigantic dimensions. To free up hard disk space without sacrificing the content of the MKV file, it is common to convert it to a lighter format that preserves the audio and video quality.
  • Sharing the file – An MKV file is usually very heavy and therefore difficult to share over the Internet. To facilitate this process it is necessary to convert the file to other formats such as AVI or MP4.
  • Compatibility issues– The vast majority of Smart TVs do not support the MKV format. If we are thinking of playing on our TV some kind of content downloaded from the Internet in this format, we will first need to convert it to AVI or MP4.
