What is a MKV file?

MKV (Matroska) is a flexible open container that holds high-definition video, multiple audio tracks and subtitles in one file. It is popular for movies and archiving, but is not natively supported by every device or browser.

How to open a MKV file

MKV plays in VLC and most modern media players; some phones, browsers and TVs need it converted to MP4 first.
