MKV is the format that hoards: video, a dozen audio tracks and every subtitle, all in one box. The Matroska container: it will hold practically any codec ever made.

- 2002, the open-source Matroska project
- Type

- Typical size

- VLC and desktop players love it; smart TVs, Apple devices and editors often don't.
- Fun fact
- Matroska is named after matryoshka nesting dolls: a container built to hold containers.
What this MKV converter flips
Two directions, one page. Outbound: move MKV into MP4, WEBM or another container when MKV proves weak at playing on TVs, iPhones and editors that never learned to open the box: or pull just the audio out as MP3 or WAV. Inbound: re-wrap other footage as MKV when a tool demands it.
Everything MKV converts to
