How to convert MP4 to MP3

Converting a video to MP3 takes three steps, all in your browser: drop your MP4 (or MOV, WEBM, M4V) file onto the upload area, pick a bitrate - 320 kbps for best quality - and hit convert. The audio track is extracted locally and downloads as an MP3, or as a ZIP if you convert several files at once. Nothing uploads to a server.

Video to MP3 for any format

MOV to MP3 - MOV is the default recording format on iPhone and QuickTime. It decodes in every modern browser, including Safari, so drop it in like any other video.

WEBM to MP3 - WEBM shows up in screen recordings and browser captures. It decodes in Chrome, Firefox and Edge, but not in Safari - switch browsers if the file will not load.

M4V and MKV - Support for these is best-effort and depends on your browser's codec support. MP4 and MOV are the safest bet if a file will not decode.

Why extract audio from video

Video-to-MP3 extraction covers a handful of common cases: pulling the audio from a DJ set recorded on a phone, ripping a livestream to re-edit later, grabbing a sample from a piece of footage, or turning a video interview into a podcast clip. In every case you only need the sound - stripping the video track keeps the file small and easy to share.

Your video never leaves your device

Extraction runs entirely client-side using the Web Audio API - the video file is decoded and re-encoded in your browser, never uploaded to a server. That also means no upload queue to wait through, and once the page has loaded the converter keeps working even without an internet connection.

MP4 to MP3 at the right bitrate

320 kbps is near-transparent quality for music and the safe default for extracting audio from video. Use 192 kbps if you want to save some space without a noticeable drop in fidelity, or 128 kbps for voice recordings, interviews, and podcast clips where file size matters more than fidelity.
