Where your MP4 came from
An MP4 is what a phone, a camera and every video site produce. Its audio track is AAC and it is a fraction of the file.

Why you are converting it
Nothing refuses an MP4. What refuses is the situation: a podcast host, a transcription service or a music player that wants sound and not a picture. WAV is uncompressed samples with a forty four byte header. Editors, samplers and anything that has to process rather than play the audio want it.

What it costs
Nothing further is lost going into WAV, because nothing is thrown away. What an earlier encode discarded is still gone, and a large file does not bring it back.
FAQ
- How do I convert MP4 to WAV?
- Drop the file on this page and press the button. It runs in your browser, so there is no upload, no account and no daily limit.
- Why will my device not open a MP4 file?
- Nothing refuses an MP4. What refuses is the situation: a podcast host, a transcription service or a music player that wants sound and not a picture.
- Is there anything odd about MP4?
- Separating the audio does not re-encode the picture, because the picture is discarded rather than converted. That is why this takes seconds on a file that would take minutes to transcode.
- Does converting to WAV lose quality?
- Nothing further is lost going into WAV, because nothing is thrown away. What an earlier encode discarded is still gone, and a large file does not bring it back.
- Is the file uploaded?
- No. The decode and the encode both happen in the page, and no request carries the audio anywhere. Watch the network panel while it runs.
