About MP4 to WAV
MP4 to WAV extracts the soundtrack from an MP4 video and saves it as WAV.
Upload the MP4 file, start extraction, and download the WAV audio. You do not need to install a video editor or learn a timeline just to separate sound from picture.
Choose this tool when the video container is fine but you need a standalone audio file for players, transcripts, or editing. The source video should include an audio track; silent videos cannot produce useful audio output.
Example workflow
Use MP4 to WAV when your player, editor or upload form requires WAV rather than MP4. Re-encoding can change file size and quality. A lossless output cannot restore details already lost in a compressed source.
Output checks and limits
Accepted inputs: MP4. The current processing duration limit is 30 minutes. The upload size shown for your plan also applies; codec compatibility and processing time can still limit a job. Check playback, duration and sound in the downloaded file before deleting the original.
Benefits of MP4 to WAV
Frequently asked questions
Can I extract audio from MP4 online?
Yes. MP4 to WAV reads the file and encodes a WAV audio download when a soundtrack is present.
What if the video has no sound?
Extraction cannot create audio that was never recorded. Use a source with an audio track.
Why WAV?
WAV is widely supported in players and editors, which makes it a practical default for extracted sound.
