How to convert a video to MP3 (free)

1. Drop your video onto the box above — MP4, MOV, WebM, MKV and most other formats work.
2. Pick an MP3 bitrate. 192 kbps is a good all-round default; 320 kbps is the highest quality.
3. Click Convert to MP3. The result previews with a player and downloads when you click save.

Why extract audio from a video?

Turn a lecture recording, interview, podcast video, concert clip or music video into a plain MP3 you can play in any music app, drop into a podcast feed, or listen to offline. FFmpeg reads the audio track straight from the container and discards the video stream, so there is no quality loss beyond the MP3 encode itself.

Which bitrate should I pick?

• 128 kbps — smallest files; fine for speech, podcasts and lectures.
• 192 kbps — the safe default; transparent for most listeners on most music.
• 256 kbps — high quality with modest file size.
• 320 kbps — the highest MP3 bitrate, for the best fidelity the format allows.

Real FFmpeg, running in your browser

This tool ships FFmpeg compiled to WebAssembly, so extraction happens inside your browser tab. Your video is never uploaded: nothing to leak, cache on a server, or delete later. The first run downloads the engine once, which the browser then caches. Because your own device does the work, longer videos take a little longer — but nothing ever leaves the page.

Is there a file size limit?

Only your device's memory. Full-length videos and hour-long recordings are fine on a typical laptop, and extraction runs at many times real-time speed.

Need WAV, FLAC, Opus, or to trim the clip?

The Audio Converter handles every audio format, lets you trim a start and length, and also extracts audio from video. This page is the shortcut when you just want an MP3.
