How to Extract Audio from Any Video for Free

Whether you want to save a podcast episode that was uploaded as a video, grab a song from a performance, or create a voiceover track, extracting audio from a video is a highly useful skill. You don't need expensive video editing software to do this.

The Old Way vs. The New Way

In the past, you either had to download desktop software like VLC or Audacity, figure out their complex export menus, or rely on sketchy online converters that bombarded you with ads and forced you to upload your files to their servers.

Today, thanks to WebAssembly, you can extract audio from an MP4, WebM, or MOV file directly in your web browser. This means the file never leaves your device, keeping the process private and lightning fast.

Step-by-Step Guide

1. Open the Audio Extractor tool on OpenToolbox.
2. Drag and drop your video file into the designated area.
3. Select your desired audio format (MP3 is best for general use, WAV is best for high-quality, lossless audio).
4. Click the extract button.

Within seconds, your browser will process the video, strip out the visual data, and provide you with a clean audio file ready for download. This entire process happens locally, so you don't even need a fast internet connection!
