Matroska Video
Matroska is an open container that will hold any codec, unlimited audio tracks, chapters and embedded subtitles. That flexibility is why it dominates archival video and why hardware players so often refuse it.

Opening a .mkv file
If you landed here because something handed you a .mkv file and
nothing on your machine will open it, converting it to a format you already have a
reader for is usually faster than installing new software. Every conversion above runs
in this browser — the file is not uploaded, so it works on a locked-down work machine
and on a file you are not allowed to send anywhere.
