How to Extract Audio from Video

  1. Add your video - Click the drop area or drag and drop your video file (MP4, WebM, MOV, AVI).
  2. Choose output format - Select MP3 for compressed audio or WAV for uncompressed quality.
  3. Extract - Click "Extract Audio" and wait for processing.
  4. Download - Save your extracted audio file.

Common Use Cases

Most people arriving at this tool are doing one of a handful of things: turning a recorded lecture or webinar into something they can listen to while commuting, pulling the dialogue track out of a project to edit or transcribe, saving the audio from a screen recording of a meeting, rescuing a voice note that was accidentally captured as video, or grabbing a track to feed into our Audio Trimmer for a ringtone. In every case the video file is just packaging; this tool unwraps it.

The rule of thumb: if a human is going to listen to it, MP3; if software is going to edit it, WAV. When unsure, WAV loses nothing and can always become an MP3 later, while the reverse trip cannot restore what MP3 discarded.

How the Extraction Works

There is no server-side transcoder involved. Your browser already contains a full video decoder (it is how it plays video at all), and the Web Audio API exposes the decoded audio samples to the page. This tool reads those samples straight out of the decoder and writes them into a fresh MP3 or WAV file, all inside your tab. That architecture is why the supported-formats list matches whatever your browser plays, why big files depend on your device's memory, and why nothing you extract is ever uploaded.

Frequently Asked Questions

What video formats are supported? MP4, WebM, MOV, AVI, and most browser-supported video formats. The practical test is simple: if your browser can play the video, this tool can extract its audio, because it uses the browser's own decoder to read the track.
Where does the extraction happen? Entirely on your device. The browser's Web Audio API decodes the video's audio track in local memory and the MP3 or WAV file is assembled right there, so the video itself is never transmitted anywhere. Screen recordings of private meetings and unreleased footage stay exactly as private as they were before.
Is there a file size limit? The ceiling is your device's memory rather than a fixed number. Most modern computers handle videos up to about 500 MB comfortably; phones tap out earlier. If a large file fails, trimming the video down first or switching to a desktop browser usually solves it.
Can I extract just one section of the audio? This tool pulls the complete track in one pass. To keep only a section, extract the full audio here first, then open the result in our Audio Trimmer and cut it down; both steps stay in your browser.
Why is my extracted audio quiet or mono? The extraction preserves whatever the video contains. Phone recordings and screen captures are often recorded quietly or with a single microphone channel, and that carries through. Our Volume Booster can raise the level afterward if the source was low.
Does extracting reduce the audio quality? WAV output is a bit-for-bit rendering of the decoded track, so nothing is lost. MP3 output re-encodes at 128 kbps, which is transparent for speech and casual listening. For music you plan to edit further, choose WAV and compress later if needed.
