Free tool

Extract the audio from a video as MP3, M4A or WAV, in your browser

Drop in a video, pick a format and download just the sound. Everything runs on your device, so your video is never uploaded.

Your file never leaves this browser tab. Nothing is uploaded.

MP4, MOV, MKV, WebM and most other video files. Up to 500 MB.

Keep the sound, skip the upload

You recorded a video call or an interview and only need the audio for a podcast, a transcript or an editor. This tool pulls the main audio track out of the video and saves it in the format you choose.

It uses ffmpeg compiled to WebAssembly. A video can be large, and with this tool it never has to leave your computer.

How to use it

#how
  1. Choose a video

    Drop an MP4, MOV, MKV, WebM or most other video files (up to 500 MB) onto the box or pick one from your device.

  2. Pick a format

    MP3 is the safe default, M4A is a little smaller, WAV keeps everything for editing. Tick mono for a single voice.

  3. Extract and download

    The tool shows the size before and after. Play the audio if you like, then download it.

Which format to choose

#formats

M4A (AAC)Apple devicesA little smaller than MP3 at the same quality.
WAVEditing and transcriptionUncompressed, so the file is large.

Good to know

#tips
  • The tool uses the main audio track of the video. If a video has several tracks, it is the first one.
  • Choose WAV if you will edit further, then convert to MP3 once at the end.
  • A one-hour video is mostly picture: the audio is often a tenth of the file or less.
  • If the extracted audio has background noise, run it through the noise remover next.

What happens to your file

#privacy

The file is read and processed by your browser using ffmpeg compiled to WebAssembly, and the result is written back as a download. It is not sent to Airtape or any other server, and it is not stored. You can check this in your browser's network tab: no request carries your file.

The converter engine is about 30 MB. Your browser downloads it the first time you convert a file and then keeps it, so later runs start right away. Files are limited to 500 MB because a browser has limited memory.

Frequently asked questions

MP3 and M4A are re-encoded, which loses a little quality, so use the High setting for important material. WAV keeps the audio as it is in the video.

Yes, 500 MB per file, because a browser has limited memory.
