Drop a video and its audio track is extracted and encoded to MP3 on your device — nothing sent anywhere.
Drop a video and its audio track is extracted and encoded to MP3 on your device — nothing sent anywhere.
Extract the audio from a video as an MP3, in your browser. A lecture recording, an interview, a concert clip, a voice memo that ended up as video — drop the file and GhostVideo pulls the audio track and encodes it to MP3 on your device. No upload, no signup, no length cap beyond your browser's memory. The video never touches a server, which makes this safe for meetings and private recordings.
How it works
Drag in an MP4, MOV, or WebM. It opens in the GhostVideo studio with Extract MP3 pre-selected.
ffmpeg runs in your browser, pulls the audio track, and encodes it as MP3 — nothing is sent anywhere.
Save it — or keep going: trim it or compress it further in the GhostAudio studio.
No — extraction and encoding run in your browser via WebAssembly ffmpeg.
The common ones — MP4, MOV, WebM, MKV. If your phone or screen recorder made it, it almost certainly works.
MP3 is lossy, so technically yes, but at the encoded bitrate the difference from the source track is inaudible for speech and most music.
Extract the full MP3 first, then Trim it in the GhostAudio studio — same tab, no re-upload, because there was never an upload.
No fixed cap — hour-long lectures are fine on a typical laptop; the work runs in your browser's memory.
Compress video
Shrink phone footage to shareable size — encoded on your device.
Trim video

Every GhostVideo tool runs entirely in your browser. Your file is never uploaded — there's no upload endpoint to send it to.
