Why Convert MP4 to WAV?

MP3 is fine for listening and wrong for working. Every edit on a compressed file re-compresses it, and by the third pass you can hear it. WAV holds raw PCM samples with nothing thrown away, so audio pulled out of an MP4 lands in Logic, Audacity, or Premiere in the state the video had it.

The file is big. That is the trade, and for editing it is worth it.

Frequently Asked Questions

How large will the WAV be?
Roughly 10 MB per minute for stereo at CD quality. A one hour recording lands near 600 MB, so keep an eye on disk space.
Does the browser really do this locally?
Yes. The MP4 is decoded with WebCodecs and the WAV is written in the tab, which is why the page keeps working with the network off. Anything over 500 MB routes to the desktop app.
Is any quality lost?
Nothing is lost on the WAV side, since it stores the decoded samples uncompressed. Whatever compression the MP4's audio track already had is baked in and cannot be undone by converting.
Can I extract just one section?
Yes. Trim the clip in the editor first and only that range is written out.
Is my file private?
Yes. The conversion runs in your browser tab and nothing is uploaded, so your files never leave your device. The only limit is size: 500 MB for this format. Bigger files route to the desktop app.

Pulling audio from a shoot?

The desktop app extracts WAV from every clip in a folder at once through FFmpeg, with no 500 MB cap and no upload.
