Convert MKV to WAV
Free online MKV to WAV converter that runs in your browser. Your files stay on your device.
How to convert MKV to WAV
- Add your MKV file. Drag it onto the box above, click to browse, or paste it from the clipboard. Multiple files are fine.
- Check the target. WAV is preselected. Pick High, Medium or Small quality depending on whether you need a master copy or a small file.
- Download. The conversion engine loads once (32 MB) and then your file is processed locally. The WAV file downloads automatically when it is done.
Why convert MKV to WAV?
Extracting the audio from a MKV video gives you a WAV file you can play in a music app, use as a ringtone, or edit in a podcast tool without the video overhead. A 500 MB video typically becomes a 5–10 MB WAV.

What makes this converter different
- Nothing is uploaded. Other converters send your file to a server, queue it, and keep a copy for hours. Here the work happens in your browser with WebAssembly, so private videos, voice memos and documents never leave your computer.
- No limits, no sign-up, no watermark. There is no server to pay for, so there is no reason to cap file size or count.
- Real ffmpeg quality. Video and audio use the same ffmpeg encoders professionals use (x264, LAME, libvpx, FLAC), not a stripped-down web codec.

Frequently asked questions
Is it safe to convert MKV to WAV here?
Yes. The conversion runs entirely inside your browser using WebAssembly. Your file is never uploaded to a server, so nothing can leak, be stored or be seen by anyone. You can even disconnect from the internet after the page loads.
How long does MKV to WAV conversion take?
Video encoding in the browser runs at roughly 0.5–2× real time depending on your CPU and resolution. A 1-minute 1080p clip takes about 1–2 minutes. Long or 4K videos can take a while; a desktop computer is much faster than a phone.
Is there a file size limit?
There is no server-side limit because there is no server. The practical limit is your device memory: browsers can handle files up to about 2 GB. Very large videos work better on a desktop than a phone.
Will the quality drop?
WAV is lossless, so no quality is lost relative to the source. It cannot recover detail that a lossy source already discarded.
Can I convert several MKV files at once?
Yes. Drop or select as many files as you like; they are converted one after another and each gets its own download button.
