Before you pick up the best MKV to AVI converter that suits you most, there is something you should know about MKV and AVI.

MKV and AVI are two different video container formats used for storing audio and video files. Have you ever noticed that sometimes you can switch subtitles and language in different languages when playing MKV movies? That's one of the most favored features of MKV. This advanced multi-media container has good fault tolerance and compatibility which is capable of holding an unlimited number of high-resolution video, audio, image, and subtitle tracks in a single file.

However, what makes MKV great is also its biggest downfall, for example

  • Many devices won't play MKV files correctly, for instance, iPhone, iPad, and some prevalent TVs.

To save space for your hard disk, and enjoy the stunning videos on the go, you need a good MKV to AVI converter to convert MKV to AVI or any other. So read our round-up of the top 6 MKV to AVI online and desktop converters.
