How to Extract Audio from Video (Any Format to MP3)

You don't need the video — just the sound. Upload any video file and download only the audio track as MP3. Upload to MegaConvert.io and select MP3 — done in seconds, free.

The Problem

You recorded a video interview but only need the audio for a podcast. Or you want the soundtrack from a concert video. Or you need to listen to a lecture recording while driving.

Why Convert?

• Podcasts — record video, publish audio-only.
• Music — extract audio from music videos.
• Lectures — listen while commuting.
• Storage — audio is 10-20x smaller than video.

How to Convert Online

1. Go to megaconvert.io/mp4-to-mp3.
2. Drag and drop your .mp4 file.
3. Download your .mp3.

No account. No watermarks. Files auto-delete after 1 hour.
