How to extract MP3 audio from a video

Maybe you only want to listen to a lecture, keep the sound from a concert you filmed, or review the audio of a recorded meeting. Extracting the audio track as an MP3 makes the file much smaller and lets you play it in any music app.

Extracting the audio

1. Add a video file to the Video to MP3 tool below. Any format your browser can play, such as MP4, WEBM or MOV, works.
2. Choose an output format. MP3 suits most people. Pick WAV if you need an uncompressed copy for editing.
3. Click extract. The audio is pulled out directly without replaying the video, so it usually takes a few seconds.

MP3 or WAV?

Choosing a bitrate

Bitrate is how much data is used for each second of sound. Higher numbers mean better quality and bigger files.

• 64 to 96kbps: enough for speech such as lectures and meetings.
• 128kbps: the most common choice, fine for music too.
• 192 to 320kbps: for keeping music at high quality.

Saving at a higher bitrate than the source does not improve the sound. It only makes the file larger.

Polishing the audio afterwards

To shrink an MP3 you already have, or to turn M4A, WAV or OGG files into MP3, use the Audio Converter. You can set bitrate, sample rate, and mono or stereo. Converting speech-only audio to mono roughly halves the size.

Please keep in mind

• This tool works only with video files on your own device. It does not download videos from streaming sites.
• Extracting and sharing audio from music or videos made by others can infringe copyright. Use it only for videos you made or have permission to use.
