Free Online Audio Extractor
Lift the audio track out of any video as a ready-to-share MP3 — runs in your browser via WebAssembly, no upload, no watermark, no signup. Works with MP4, MOV, WebM, AVI and MKV.
Features
One-Click Audio Extraction
Drop a video, hit one button, get an MP3 back. No format juggling, no settings — upload, extract, download.
Clean MP3 Output
Encoded with LAME at VBR quality 2 — transparent for speech, music and podcasts, around 190 kbps average.
Handles Any Container
MP4, MOV, WebM, AVI, MKV and FLV all work. Whatever codec the audio track is in, you get MP3 out.
Smaller Than the Video
The extracted MP3 is a fraction of the original file size — perfect for podcast drafts, meeting notes or mobile sharing.
Podcast-Ready Quality
MP3 at VBR quality 2 is the sweet spot for voice content — indistinguishable from the source but small enough to upload anywhere.
Voice-Optimized Encoding
LAME's VBR mode allocates more bits to complex passages, so spoken word stays natural without bloating file size.
Faststart MP3
Output writes an instant-seek header so the audio plays back immediately in browsers, players and podcast apps.
Seconds, Not Minutes
Audio-only re-encode runs dramatically faster than video processing. A one-hour lecture extracts in under a minute.
100% Private & Free
Your footage never leaves your device. Everything runs in the browser tab using WebAssembly — no server, no upload, no tracking.
Zero Server Upload
Files are read, processed, and written back entirely on your own machine. We never see your video or the audio you extract.
No Watermark
The exported MP3 is clean — no audio intro, no branding tag, no logo. Your audio, untouched.
Works Everywhere
Any modern browser — desktop or mobile. Chrome, Firefox, Safari, Edge.
