Quick answer: To extract audio from a video, add the video and choose M4A (AAC sound usually copied without re-encoding), MP3 for any player or WAV for editing, then download one audio file per video. It works with iPhone videos and runs in your browser.
Keep the talk, the song or the interview and drop the picture. Choose MP3 for any player, M4A for the best quality per MB (often copied without re-encoding), or WAV for editing.

How to extract audio from video
- Choose or drop one or more videos.
- Pick MP3, M4A or WAV, and the quality.
- Press Extract audio.
- Play the audio on the page, then download it or send it with a link.
Which format to choose
| Format | Best for | Size per minute |
|---|---|---|
| MP3 | Any player, car stereos, podcasts apps | About 1.4 MB at 192 kbps |
| M4A (AAC) | iPhone, iTunes, the best quality per MB | Same as the video's sound when copied |
| WAV | Editing in an audio or video app | About 10 MB |
Most MP4 and MOV videos store their sound as AAC. With M4A the tool copies that sound track as it is: no quality loss, and it takes seconds even for a long video.
Good uses
- Turning a recorded talk, lecture or interview into a podcast episode or an audio file for transcription.
- Keeping the music or voice from a phone video.
- Sending a small audio file instead of a huge video when only the sound matters.
Only extract audio you have the right to use.
On your device, in the browser
The video is read in pieces by your browser, only the sound is decoded, and MP3 is encoded with the LAME encoder compiled for the web. Nothing is uploaded. Need the silent video instead? Use Mute video.

Frequently asked questions
Is the extracted audio the same quality as the video's sound?
With M4A, usually yes: AAC sound is copied without re-encoding. MP3 is re-encoded; at 192 kbps or more it sounds the same to most listeners.
Can I extract audio from several videos at once?
Yes. Add them all; you get one audio file per video, and can download them as a ZIP.
Does it work with iPhone videos?
Yes. The sound in iPhone videos is AAC, which every current browser can read, even when the video itself is HEVC.
Is my video uploaded?
No. The audio is extracted on your device.
