Why it doesn’t play
MKV plays only sometimes: Windows needs paid or extra extensions for some codecs, and browsers skip many of them. That is why one MKV file plays and the next shows a black screen or no sound.

Play it free with PlayAnyVideo
- 1
Open the PlayAnyVideo player in your browser — nothing to install — and drop the file in. Files never leave your device.
- 2
If the browser can’t decode it, the built-in universal engine (open-source, LGPL) takes over automatically.
- 3
For the heaviest files (4K/8K HEVC, DTS, TrueHD) install the free Windows app: it converts on the fly with your graphics card and plays everything.
- 4
On Android, choose “Open with → PlayAnyVideo” from your file manager or messenger.
FAQ
Is it really free?
Yes. PlayAnyVideo has no ads, no paid codecs and no locked features.
Is my MKV file uploaded anywhere?
No. Playback happens on your own device; local files are never sent to a server.
Do I need a codec pack?
No. Codec packs can break other players and often bundle adware. PlayAnyVideo brings its own decoders.
