MKV to WAV
Extract WAV audio from MKV video — right in your browser, nothing uploaded.
Drag & drop your MKV files here, or click to choose. Everything runs in your browser — nothing is uploaded.
MKV (Matroska) is an open video container; this tool pulls the audio track out of the video. People convert MKV to WAV because audio editors, DAWs and CD-burning tools work best with uncompressed WAV. This free MKV-to-WAV tool pulls the audio track out of your MKV video and saves it as WAV, entirely inside your browser using a WebAssembly build of FFmpeg, so nothing is uploaded. Drop in one file or a whole batch, and each file converts automatically — then preview every result in place and download it. No signup, no watermark, and nothing to install.
Frequently Asked Questions
How do I convert MKV to WAV?
To convert MKV to WAV, drag your MKV files onto the drop area or click to choose them, and each converts to WAV automatically the moment it is added — there is no format to pick and no convert button. When a file finishes it appears as a row with its new name, size, an inline player to preview it and a Download button, and everything runs in your browser so nothing is uploaded.
Is this MKV to WAV converter free and private?
Yes on both counts: it is completely free with no signup, no watermark and nothing to install, and it is private because the whole conversion runs on a WebAssembly build of FFmpeg inside your own browser rather than on a server, so your files never leave your device. That makes it safe for private or unreleased recordings. The only download is the converter itself, a one-time roughly 32 MB file that is cached afterwards.
Will converting MKV to WAV lose quality?
The WAV file itself loses nothing, because WAV is lossless and stores exactly the audio it is given. But MKV is already a lossy format, so converting to WAV cannot restore detail the MKV encode already discarded — it simply stops any further loss, and the file becomes noticeably larger. It is best when you want a lossless master to edit or archive from here on.
Why convert MKV to WAV?
People convert MKV to WAV because audio editors, DAWs and CD-burning tools work best with uncompressed WAV. WAV is uncompressed PCM audio — perfect quality but large files, and playable on virtually everything. Converting re-packages your existing MKV audio into WAV so it drops straight into that device, app or workflow, without changing how the original was recorded.
Is there a file size or number limit?
There is no fixed size or count limit, because nothing is uploaded — you can drop many MKV files at once and each is converted separately with its own preview player and Download button. The only real limit is your device’s memory, so very large files of several hundred megabytes convert more comfortably on a desktop than on a phone.
Does it keep the video?
No — this tool takes only the audio track out of your MKV file and discards the video, giving you a pure WAV audio file. That is exactly what you want for saving a song, a podcast or the soundtrack from a clip. If you need the video too, keep your original MKV file alongside the extracted audio.
