How to extract audio from a video

  1. 1

    Add a video, such as an MP4 or MOV.

  2. 2

    Pick the audio format you need.

  3. 3

    Download the audio.

Which format to save

MP3 plays everywhere: phones, cars, podcast apps, and upload forms. M4A suits Apple devices. FLAC keeps every detail in a smaller file than a WAV, and OGG and Opus are small, for the web and for speech.

Most MP4 and MOV videos carry AAC sound: pick M4A and it's copied exactly as it is, with nothing lost, in seconds. The sound in a WebM is usually Opus, which the Opus choice copies the same way. WAV and FLAC lose nothing more either, but they make a bigger file: WAV runs to about 10 MB a minute at CD quality.

Questions

Is it free?

Yes, for the first hour of each file, 10 times a day, with no sign-up. For longer files, see pricing.

Does it change the sound?

No. You get the video's sound at its own level, with nothing added, cut, or made louder. For noise or a quiet voice, send it on to Remove noise or Boost volume.

What if the video has several sound tracks?

You get the first one. Most phone videos and screen recordings carry only one.

How long can the video be?

Up to 10 hours. Without an account, files up to 100 MB work, and signed in, up to 10 GB.

Can I keep just part of the sound?

Yes. Extract it here, then trim it with the audio trimmer.

How is it different from MP4 to MP3?

MP4 to MP3 gives you an MP3 straight away, and MP4 to WAV a WAV. Here you choose the format first, such as M4A to copy the sound exactly, or FLAC to keep every detail in a smaller file.

Can I do it on my phone?

Yes. Open this page in your phone's browser, choose the video from your photos or files, and download the sound.

What happens to my files?

They stay private. Files are deleted after 24 hours, and free results after 1 hour.
