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.
