The fastest way is to use a free browser-based tool no software to install, no account needed.

Here's how it works with Livestorm's converter: Go to livestorm.co/tools/convert/mp4-to-mp3
1. Upload your MP4 file Click convert, then download your MP3 That's it.
2. The tool extracts the audio track from your video and gives you a clean MP3 file in seconds.

It works on Mac, Windows, and Chromebook, right in your browser, with no watermark and no hidden fees.

When you convert MP4 to MP3, we extract the audio track from your video file and save it as a standalone audio file. The video portion is removed, leaving only the sound. This creates a smaller, more portable file that's perfect for music players, podcasts, and audio-only sharing. Your audio quality is preserved based on the original video's audio track.

MP4 - Video container format, larger file size (varies by video quality and length), contains both video and audio, requires video players

MP3 - Audio-only format, much smaller file size (typically 1MB per minute at 128kbps), plays on all music players, phones, and audio devices

Converting removes the video track, creating a lightweight audio file that's easier to store, share, and play on any device.

128 kbps - Standard quality, smaller file size (~1MB per minute), suitable for podcasts and spoken content

192 kbps - Good quality, balanced size (~1.5MB per minute), great for most music and audio

256 kbps - High quality, larger files (~2MB per minute), recommended for music with detailed sound

320 kbps - Maximum quality, largest size (~2.5MB per minute), best for audiophiles and professional use

Note: Output quality cannot exceed the original MP4 audio quality. If your video has 128kbps audio, converting at 320kbps won't improve it.

Audio quality depends on the source. If your MP4 video has high-quality audio (256-320 kbps), we preserve that quality in the MP3. If the video audio is lower quality (128 kbps), the MP3 will match that quality.

We don't improve or reduce quality - we simply extract what's already there. For best results, convert videos that have clear, high-bitrate audio tracks.

File size will decrease significantly because we're removing all video data and keeping only the audio stream.
