Extract sound from videos or audio files as MP3 / WAV / AAC / OGG
About this tool
Pulling the sound out of a concert recording, a podcast video or a lecture capture so you can listen on the go is a classic move. This tool reads any common video - MP4, AVI, MKV, MOV, WebM, FLV and friends - and saves its audio track as MP3, entirely inside your browser, with nothing uploaded.
Extraction has two paths. If the track inside the video already is MP3 (very common in AVI and downloaded files), it is copied out untouched: bit-identical quality, done in seconds. Otherwise the audio is decoded and re-encoded with LAME at the bitrate you pick - 128, 192 or 320 kbps, the top tier being CD-grade for the format.
Audio extraction is an order of magnitude faster than video conversion because no frames are touched: a several-minute recording typically yields an MP3 in a dozen seconds, with an inline player to audition before download.

Frequently asked questions
- Lossless copy or re-encode - what is the difference?
- Lossless copy only applies when the video already carries an MP3 track: the raw MP3 data is lifted out of the container untouched, bit for bit, in seconds. AAC, Opus or other tracks must be decoded and re-encoded with LAME - choose 320 kbps for the highest quality the format offers. Automatic preference for lossless is on by default.
- Which bitrate should I choose: 128, 192 or 320?
- 320 kbps is the top MP3 tier, CD-grade for practical purposes - good for archiving and nicer headphones. 192 kbps sounds transparent to most listeners at a fraction of the size, and 128 kbps is plenty for spoken word such as podcasts and audiobooks.
- It says the video has no audio track - why?
- Some files genuinely carry no audio: surveillance clips, silent screen recordings, pure visual footage. Use the preview player to check a video has sound, or try another file.
- Does it work on phones, and are files uploaded?
- Yes - the page is responsive and you can pick videos straight from your device. And no, nothing is uploaded: there is no backend able to receive files, all work happens in browser memory after a one-time ~31 MB engine download that is cached for offline use.
