About the formats
MKV · Matroska video
MKV is a flexible open container that can hold many video, audio and subtitle tracks. It is common for films and screen recordings (OBS).
WAV · Waveform Audio
WAV is uncompressed audio, used for recording, editing and audio production. Files are large but lossless.
The conversion runs on your device using FFmpeg compiled to WebAssembly. You can adjust: sample rate, channels, normalise loudness, start at, end at.
Frequently asked questions

Are my files uploaded to a server?
No. The conversion runs entirely in your browser using WebAssembly. Your files never leave your device, so it is safe for private photos, contracts and business data. Once the page has loaded it even works offline.
Will converting MKV to WAV reduce quality?
No further quality is lost: WAV stores the result losslessly. It cannot restore detail that was already discarded when the MKV file was created.
Can I convert multiple MKV files to WAV at once?
Yes. Add as many MKV files as you like; they are converted in parallel on your device and you can download them all as a single ZIP.
Is it free? Are there limits?
It is free, with no sign-up, no watermark and no daily limits. Because nothing is uploaded there is no upload size limit either; the only limit is your device’s memory, which matters mostly for very large videos.
