Why Convert MP4 to MP3?
Save Music from Videos
Extract audio from music videos, concert recordings, live performances, or DJ sets to listen offline on your phone, MP3 player, or car stereo.
Create Podcast Episodes
Pull audio from video interviews, webinars, recorded meetings, or lectures to create audio-only podcast episodes for listeners who prefer audio.
Save Storage Space
A 1-hour MP4 video is 1-2GB. The audio track alone as MP3 is 50-100MB — a 95% reduction. Perfect when you only need the audio.

Frequently Asked Questions
Does extracting audio lose quality?
The audio is re-encoded to MP3. At 192-320kbps, quality is excellent. The original video's audio quality (usually AAC at 128-256kbps) is the limiting factor — you can't get better quality than the source.
Can I extract audio from multiple videos at once?
Yes. Upload multiple MP4 files and extract audio from all of them with the same bitrate settings.
Can I choose a specific portion of the video?
Extract the full audio, then trim with our MP3 trimmer. Or trim the video first with our video trimmer.
Is it free?
Yes. Completely free with no watermarks, no sign-up required, and no file count limits.
Does it work on mobile?
Yes. Works in any modern browser on all devices — no app installation required.
