How to extract audio from a video
Short answer
Add the MP4 to an MP4-to-MP3 converter and it separates the audio track and saves it as an MP3. Choose a bitrate for the output, then download — the video itself is left untouched.
Why extract just the audio
A video file bundles a picture track and an audio track. When you only need the sound — a talk, a song, an interview, a lecture — extracting the audio to MP3 gives you a small file you can play anywhere without the video.
Extract the audio
- Add the MP4Drop in the video file. It is processed locally in the tab.
- Choose a bitrate128-192 kbps for speech; 256-320 kbps to keep music quality.
- Download the MP3Save the extracted audio; the original video is unchanged.

Quality is capped by the sourceThe extracted MP3 can only be as good as the audio already in the video. A high bitrate will not improve a quiet or compressed source. See what is audio bitrate.
Good to know
- Extraction copies the audio; it does not alter or delete the video
- For music, use a higher bitrate; for talking, a lower one is fine
- Only extract content you have the right to use
- Other audio formats can be converted to MP3 the same way
