How do I convert MKV to WAV?

Add your MKV file to the upload area above, then press Convert. The WAV file downloads straight to your device. You do not need an account, and there is no watermark.

Are my files uploaded to a server?

No. This conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can even disconnect from the internet after the page loads and it will still work.

Does converting to WAV reduce quality?

WAV uses lossy compression, so some data is discarded. At the default quality the difference is very hard to see or hear; raise the quality setting if you need to be certain, at the cost of a larger file.

How large a file can I convert?

Up to 512 MB per file for this conversion. Because the work happens in your browser, the practical limit is your device's memory — larger files work on a desktop with plenty of RAM and may fail on an older phone.

Can I convert several files at once?

Yes. Add as many as you like and press Convert All. Each file is processed independently, so one failure does not stop the rest, and you can download everything together as a ZIP.

Can I use this on my phone?

Yes. FileTools360 works in mobile browsers on iOS and Android, including choosing files straight from your camera roll. Very large videos may run out of memory on a phone — those are better converted on a laptop.

MKV and WAV explained

Matroska is a container designed to hold essentially anything: any codec, unlimited audio tracks, subtitle tracks, chapters and attachments in one file. It is the format of choice for archiving films with multiple languages.

WAV stores uncompressed PCM audio — the raw samples, exactly as captured. A stereo CD-quality minute is roughly 10 MB, which is the price of having no compression whatsoever.

Where MKV files come from: Media archives, anime and film collections, and high-quality recordings.
Where WAV is used: Recording sessions, sample libraries and audio editing.

MKV vs WAV

The two formats solve different problems, which is why converting between them involves trade-offs rather than a straight upgrade.

MKV compared with WAV
Property	Source	Target
Compression	Container (depends on codec)	Uncompressed
Animation	Yes	—
Introduced	2002	1991
Browser support	Great in VLC and media servers, poor in browsers.	Universal.

MKV is stronger at: Holds any codec. Unlimited audio, subtitle and chapter tracks. Open and well documented.
WAV is stronger at: Perfect fidelity with zero compression artefacts. No decoding overhead, so editors scrub instantly. Universally supported.

Why convert MKV to WAV?

This is not really a format swap — it is extraction. An MKV file carries a video track and an audio track side by side, and converting to WAV discards the picture and keeps the sound. People do it to turn a lecture, interview, podcast recording or music video into something they can listen to without the video, at a fraction of the file size.

Be aware of the size trade-off: WAV is uncompressed, so expect the converted file to be considerably larger than the MKV you started with.

MKV limitations that prompt the switch: Browsers will not play it. Many TVs, phones and editors reject it. Not accepted by social platforms.
What you give up: Very large files. No standard metadata support worth relying on.

Does converting MKV to WAV reduce quality?

Both formats store the content without discarding data, so this conversion preserves it exactly. The file size may change because the two formats compress differently, but the content itself is unaffected.
