MP4 to MP3 Converter — Extract Audio, Free & Online
Pull the sound out of your MP4 videos and save it as MP3 — nothing to install, nothing to upload.
Drag and drop your files here, or click to browse.
How it works
Choose one or more MP4 videos: the tool drops the picture and encodes the audio track as MP3 (high-quality variable bitrate). Handy for keeping the music from a clip, a lecture, an interview or a podcast recorded as video.
Can I convert a large video?
Up to 500 MB per file. The longer the video, the longer it takes, because it uses your own device's power.
Why is my MP3 empty or missing?
If the video has no audio track, there is nothing to extract. Check that it has sound before converting.
Your videos never leave your device: the audio extraction runs entirely in your browser.
