What is MKV to WMV conversion?

Matroska (MKV) and Windows Media Video (WMV) are two popular video containers, but not every player or editor handles them all. This free converter reads your .mkv file, decodes its streams and re-encodes them into a valid .wmv file with widely supported codecs. The whole conversion runs in your browser, so your video stays private.

How it works

1Upload a .mkv video file.
2Choose WMV from the output format menu.
3Click Download — the video is re-encoded locally in your browser.
4Save the converted .wmv file. No signup needed.
