Video to MP3 Converter

Extract a standalone MP3 audio track from any video file — MP4, MOV, MKV, WebM, AVI and more — without uploading anything. FFmpeg.wasm runs locally, so your video stays on your device while you pick the bitrate and download.

How to use this tool

  1. 01

    Upload your video

    Any format FFmpeg supports — MP4, MOV, MKV, WebM, AVI and more. It stays in your browser.

  2. 02

    Pick a bitrate

    192 kbps is the default and works for most cases; go higher for music, lower for spoken word.

  3. 03

    Extract and download

    The MP3 contains just the audio track — preview it inline, then download.

Why this matters

Most online MP3 extractors make you upload your full video to their server, then gate the result behind ads, watermarks, or a signup. For unreleased music, NDA recordings, or a long screen capture that's both a privacy risk and slow. Stripping the audio out of an interview, podcast cut, or lecture is one of the most common edits and shouldn't cost any of that.

This runs FFmpeg in your browser, so the video never leaves your device, and the output is a clean standard MP3 that plays everywhere and uploads to any podcast host without re-conversion. It deliberately does one thing; to take a section, pair it with the Audio Trimmer afterwards.

FAQ

192 kbps is the sweet spot for spoken word — interviews, podcasts, lectures — where it's transparent at a modest file size. Step up to 256 or 320 kbps for music or anything you'll edit further, since each re-encode compounds quality loss. 128 kbps is fine only when file size matters more than fidelity.
