How to Convert MKV to AVI and Vice Versa

The MKV or Matroska format is getting more and more popular among online file sharers. It was designed as a new standard for high quality video compression, and is able to combine HD video with multiple audio tracks and subtitle tracks, which can lead to very large file sizes – over 4 GB. This becomes a problem because they don't fit on flash drives, steal a lot of disk space on your computer, and require a very powerful system for smooth playback. However, we often don’t really need all these data, so it’s important to have software at hand to convert MKV to AVI or another common format.

Below, we’ll discuss several of the best ways to transfer MKV to other formats.
