MKV vs WAV
| MKV | WAV | |
|---|---|---|
| Full name | Matroska video | Waveform Audio File Format |
| Type | Video container | lossless |
| Codec | any video + any audio (AAC, AC-3, Opus, FLAC…) | Uncompressed PCM |

| Plays on | VLC, MPV, Plex; few phones play it natively | Every desktop OS, most phones and all audio software |
MKV. MKV (Matroska) can hold almost any codec and several audio tracks. OBS recordings and many films use it.
WAV. WAV stores raw PCM samples with no compression at all. What you save is exactly what the editor sees, which is why studios and editors use it.
What happens to quality
WAV is lossless, but it can’t restore what the MKV encoder already removed. You get an exact copy of the MKV sound in a format editors accept, at a much bigger file size. Hear the difference between lossless and MP3 yourself.
Want the original audio with zero re-encoding? Extract the audio track losslessly instead.

Questions people ask
How do I convert MKV to WAV without uploading?
Choose or drop your .mkv file above. AudioKit converts it to WAV inside your browser with ffmpeg.wasm and gives you a download. The file is never sent to a server, and you can convert several at once.
Will I lose quality converting MKV to WAV?
WAV is lossless, but it can’t restore what the MKV encoder already removed. You get an exact copy of the MKV sound in a format editors accept, at a much bigger file size.
Why is the WAV file so much bigger?
WAV is lossless: 10.1 MB at 16-bit / 44.1 kHz stereo. MKV is compressed (depends on the video), so expect the WAV to be several times larger while sounding the same.
Can I convert a MKV longer than an hour?
Yes. The video is read in place rather than copied into memory, and only its audio track is decoded. A one-hour MKV usually converts in a few minutes on a laptop; phones are slower but work.
Is this MKV to WAV converter safe?
It’s about as private as a converter can be: nothing is uploaded, there is no account and no installer. The page needs a modern browser with WebAssembly (any current Chrome, Edge, Firefox or Safari).
