How it works
- Choose a videoAn MP4, MOV, WebM or MKV from your phone or computer.
- Keep MP3 or pick anotherMP3 is set by default. M4A, WAV, FLAC and OGG are one tap away.
- Save audioYou get the whole soundtrack as one file, named after the video.
How to extract audio from a video
A video file holds two tracks: the picture and the sound. The converter reads the sound track and leaves the picture out. Nothing is uploaded, and there is no size cap from us, so an hour-long lecture opens the same way as a short clip.
Video to MP3 or another format
- MP3 plays on any phone, car stereo or speaker.
- M4A suits iPhone and Mac. From most phone videos the sound is copied bit for bit.
- WAV is uncompressed, for Audacity or another audio editor.
- FLAC is lossless too, at roughly 60 % of the WAV size.
- OGG gives the smallest file of the five.
Quality in plain words
The gear offers four steps for MP3: Smaller file (64 kbps), Standard (128), Good (192) and Best (320). Good is the default and suits music. For a lecture or a voice note, Smaller file is enough: a minute of MP3 at 64 kbps is under 0.5 MB, at Good about 1.4 MB.
MP4 to MP3 without losing quality
Any MP3 is compressed again, so a tiny bit of detail goes. To keep the sound exactly as it was recorded, choose M4A. Phone videos store their sound as AAC, and M4A takes that AAC as it is, in about a second.
Only part of the sound
This page saves the soundtrack from start to end. To keep one song or one answer from an interview, open the video in the MP3 cutter. It accepts videos and lets you mark the piece to keep.

Yes. MOV, WebM and MKV open the same way, and their sound can be saved in any of the five formats.
Muted clips and many screen recordings have no sound track at all, so there is nothing to save. Choose a video with sound.
