Convert MKV to WAV.
Pull the soundtrack out of an MKV video as uncompressed WAV, with every channel of a surround mix kept.
For editing and mixing
MKV files from OBS, cameras and rips often carry audio in codecs that editors will not import directly. A WAV of the soundtrack works in every DAW and video editor.
Surround stays surround
A 5.1 track comes out as a six-channel WAV, ready for a surround mix. For a simple stereo file, use MKV to MP3.
Size change
WAV is uncompressed: about 10 MB a minute for stereo, and three times that for 5.1.

Extracting WAV from MKV
This pulls the audio track out of your MKV and encodes it as WAV; the video is discarded. WAV is lossless, so the audio is kept faithfully.

Common questions
Is it free?+
Yes. Convert MKV to WAV free. No signup and no watermark. Free covers 10 server conversions a day, up to 100 MB a file. Pro removes the daily limit and raises the file limit to 2 GB.
Is my file private?+
Your file is uploaded to a private bucket, converted on our own engine, and auto-deleted after 1 hour. It is never sent to a third-party converter.
My MKV has several audio tracks. Which one do I get?+
One track is extracted: the track marked as default, or if none is marked, the one with the most channels. If you need a different language or commentary track, make it the default track first, for example in MKVToolNix.
Is the WAV 24-bit?+
No. The WAV is 16-bit PCM, which every editor opens. A 24-bit soundtrack is reduced to 16-bit.
