How to convert MKV to WAV online

Open a Matroska MKV and export its audio as a WAV file for editing, mixing, or transcription. The MKV to WAV converter decodes the sound to uncompressed PCM in your browser, so large MKV files are never uploaded.

  1. Step 1

    Choose your MKV
    Pick a file or drop it into the converter above.

  2. Step 2

    Keep WAV
    WAV is selected; choose another audio format if you need one.

  3. Step 3

    Download the WAV
    Save the uncompressed audio when it is ready.

What to expect

Supported inputs
MKV videos and other readable video or audio files.
What happens
The video track is dropped and the first playable audio track is written as uncompressed PCM in a WAV file. WAV is selected first; you can choose another audio format.
Limits
The MKV needs an audio track this browser can decode. WAV files are large, roughly 10 MB per minute of stereo sound, and only one audio track is converted.

Questions

The first one this browser can play. The others, and any subtitles, are left out.

The WAV holds the MKV's decoded audio with no further compression. Detail removed by the original encoding doesn't come back.
