Video to Audio
Pull the soundtrack out of an MP4, MOV or WebM video as a WAV file.
Keep The Sound, Leave The Picture
Sometimes the part of a video you want is its sound: a recorded lecture to listen to on a walk, an interview to transcribe, a performance to edit in an audio program, a voice memo that happened to be filmed. This tool takes the soundtrack out of the video file and saves it as a WAV — the plain, uncompressed format every editor and device can open.
The decoding is done by your browser, the same decoder that plays the video, so any video it can play with sound it can convert. Nothing is uploaded, which also means there is no upload to wait for: a large file costs memory on your device, not time on a slow connection.
Key features
- MP4, MOV, WebM and phone videos — whatever your browser can play.
- Lossless WAV output — nothing is re-compressed, so no quality is lost.
- Mono or stereo — mono halves the file size for speech.
- Sample-rate choice — keep the original, CD quality, or a smaller speech rate.
- Preview before saving — listen to the extracted sound first.
This tool runs entirely inside your browser using native Web APIs. Your files and text are never uploaded to a server, never logged and never shared with third parties.

Frequently asked questions
Why WAV and not MP3?
Browsers can decode MP3 but have no built-in MP3 encoder, and shipping one would mean downloading a large library. WAV is lossless and universally supported; if you need a smaller file, choose mono and a lower sample rate, or convert it in an audio editor afterwards.
Why did it say no sound could be read?
Either the video has no audio track, or its audio uses a codec this browser does not decode — some MKV files and professional camera formats, for example. Try Chrome or Firefox, or re-export the video in a common format.
How big will the WAV be?
About 10 MB per minute in stereo at 44.1 kHz, and about a quarter of that in mono at 22 kHz. The exact size is shown before you download.
Is there a file size limit?
Only your device’s memory. The whole soundtrack is decoded at once, so files over a gigabyte or two may be more than a browser tab can hold.
Is my video uploaded?
No. The file is read and decoded locally by your browser and never leaves your device.
