Extract audio from video

Takes the soundtrack out of a video. Neither option re-encodes the sound, so nothing is lost along the way.

MP4 and MOV — one at a time

Where do my files go?

Nowhere. The extraction runs inside this browser tab and the video is never uploaded. Close the tab and it is gone.

M4A or WAV — which should I pick?

M4A if you just want the audio: it lifts the original track out untouched, so it is identical to what was in the video and stays small. WAV if something downstream needs plain PCM — editors and older software often do. WAV is much larger because it is uncompressed.

Does the sound quality drop?

No. M4A copies the original audio exactly as it was — bit for bit. WAV decodes it back to raw samples, which is also lossless relative to what the video contained. Neither path re-compresses the sound.

Can I get an MP3?

Not today. Browsers can decode MP3 but not create one, and we won't ship a 30MB encoder to add it. M4A is the same idea — compressed, small, widely supported — and it comes straight out of your file with no quality cost.
