Drop a video and save its soundtrack as an MP3 — extracted on your device, nothing uploaded.
Extract the audio from a video and save it as an MP3 — a lecture or talk to listen to on the go, a song from your own footage, an interview to transcribe or edit. GhostVideo drops the picture and encodes the soundtrack to MP3 at the bitrate you choose (64–320 kbps), using ffmpeg in your browser. It works with MP4, MOV, MKV, WebM, AVI, and most other formats. No upload, no signup, no watermark.
How it works
It opens in the GhostVideo studio with Extract MP3 pre-selected.
192 kbps is the default; lower bitrates suit speech.
Save it — or send it straight to GhostAudio to trim, compress, or transcribe.
Only extract what you have rights to
Pulling audio from your own recordings, lectures you're allowed to keep, or public-domain footage is fine; ripping copyrighted music from someone else's video usually isn't.
No. Extraction runs in your browser with ffmpeg.wasm; the video never leaves your device.
MP4, MOV, MKV, WebM, AVI, and most others ffmpeg can read. If a file won't open, convert it to MP4 first.
The output is always MP3 for compatibility, which means a re-encode. At 192 kbps or higher the difference is inaudible for almost all content.
Yes — Transcribe turns the speech in a video into text or SRT/VTT subtitles on your device.
Every GhostVideo tool runs entirely in your browser. Your file is never uploaded — there's no upload endpoint to send it to.
