Separate your audio track from any video file — right here in your browser, for free. Just upload your video, pick between MP3 or WAV (or more) as an output, and download the extracted audio. Works with MP4, MOV, AVI, MKV, WEBM, and more. No signup required, no watermark on the output, no software to install.

How to Extract Audio from a Video

  1. Upload your video — Click "Select Video" or drag and drop your video file into the dotted box. The tool accepts MP4, MOV, AVI, MKV, WEBM, and other common video formats.
  2. Pick your audio format:
    • MP3 — The versatile and best-known choice. Creates a compact file that plays on every device. Best for listening, sharing, and general use.
    • WAV — The audio pro choice. Uncompressed, full quality, but larger files. Best for editing, music production, or archiving.
    • And more besides.
  3. Click the extract button — The app separates your audio track from its video container. Once done, download your audio file.

Quick rule: Choose MP3 if you want to listen to it. Choose WAV if you want to edit it.

What Happens During Audio Extraction?

Every video file is a container that holds two separate streams: a video stream (the moving picture) and an audio stream (the sound). When you "extract audio," the tool opens that container, pulls out just the audio stream, and saves it as a standalone file. It doesn't damage the original file — it just creates a new one in an audio-only format.

This is why extraction is so fast — the tool doesn't need to re-encode the video. It just reads the audio data and writes it to a new file.

If you choose WAV: The audio is saved without compression. What you get is exactly what was in the video — same quality, same fidelity. File sizes are larger, but nothing is lost.

If you choose MP3: The audio is compressed using lossy MP3 encoding. This makes the file much smaller (typically 90% smaller than WAV) with a slight quality reduction that most people can't hear in normal listening.

When to Use an Audio Extractor

Turn a Meeting Recording into an Audio File

Zoom, Teams, and Google Meet recordings are typically video files — often 300–500MB for an hour. If you only need to reference what was said, extract the audio as MP3. The file will be a mere 20–30MB and you can listen to it anywhere.

Pull Audio for a Podcast

Recorded your own video interview or webinar? Extract the audio track and publish it as a podcast episode on Spotify, Apple Podcasts, or any other platform. Saves you the time of re-exporting and the audio quality is identical.

Get a Voiceover Track for Editing

If you recorded a voiceover inside a video but need the audio separately, extract it as WAV and import it into your audio editor or DAW (Audacity, GarageBand, Adobe Audition, Logic Pro, etc.).

Save Space on Your Phone

A typical iPhone video at 1080p uses about 130MB per minute. If you recorded a conversation or voice memo as a video, extract the audio and delete the video. The MP3 will be under 2MB per minute — over 98% smaller.

Create a Transcription

Many transcription tools (Otter.ai, Descript, Google Docs voice typing) work better with audio files than video files. Extract the audio here first, then upload the MP3 to your transcription service.

Separate Audio for Video Editing

Working in a video editor and need the audio track as a separate file? Extract it as WAV (lossless), make your edits, then layer it back in. This gives you more control than editing audio within the video editor.

MP3 or WAV? Quick Decision Guide

MP3 WAV
File size Small (~1 MB per minute) Large (~10 MB per minute)
Quality Good (lossy compression) Highest (no compression)
Plays on Everything Everything
Best for Listening, sharing, podcasts, mobile Editing, production, archiving
Choose this if You want to listen to it You want to edit it

If you're not sure, MP3 is the right choice. It works for 90% of people in their daily lives. WAV is really just for professional audio work where you need to retain the original quality.
