MP4 is the most widely supported video container in the world, playable on every phone, browser, TV and editing app, and its audio track is usually AAC audio. This tool decodes that track and writes it as WAV. The video stream is simply skipped, so the process is fast even for long recordings.
WAV is lossless and large: about ten megabytes per minute of stereo audio. Pick it when you plan to edit the audio further or need a master copy.
How to convert MP4 to WAV
- Drop the MP4 file. The audio track is detected and shown with the file details.
- Keep WAV selected. WAV has no quality setting, it is always lossless.
- Extract and download. Preview the audio in the page and save it.

Questions people ask
Does MP4 to WAV keep the original audio quality?
Yes. WAV stores the decoded audio without any compression, so nothing is lost after decoding.
Is there a length limit?
No. Because only the audio is processed and nothing is uploaded, an hour-long recording takes well under a minute on a typical laptop.
Can I extract only a section?
Trim the video first with the trim tool and extract the audio from the result. Both steps run on your device.
Where does the file go?
Nowhere. It is read from your disk, processed in memory, and the result is offered as a download. Close the tab and nothing remains.
