How to Extract Audio (MP3) From a Video
Want just the sound from a video - a lecture, interview, or song? Extracting audio pulls the soundtrack into an MP3 or other audio file. Here is how it works and how to do it.
Extracting audio is not a normal conversion
A video file contains both a picture track and a sound track. 'Converting' a video to MP3 does not really change the video's format - it discards the picture and keeps only the audio. That is why we handle it with a dedicated Extract Audio tool rather than a one-click format swap: you are separating one stream from a file that holds several.
When you would want to do this
Extracting audio is useful in lots of everyday situations:
- Saving a lecture or webinar recording as an audio file to listen on the go.
- Keeping the soundtrack or dialogue from a video clip.
- Turning an interview recorded on video into a podcast-ready audio file.
- Grabbing a voice memo captured in a video.
Choosing the right output format
MP3 is the best default - small and universally playable. If you plan to edit the audio, a lossless format like WAV preserves more detail. For Apple devices, M4A (AAC) is a natural fit. Remember that extracting to a lossless format will not add quality the video's audio never had.
How to extract audio online
Open the Extract Audio tool, upload your video, pick your output format, and download the audio file. It runs in your browser, so for many files the video never has to leave your device - good for privacy.
