Question 1

How do I extract audio from a video?

Accepted Answer

Upload or drag your video file, pick the output quality and format, then click Extract. The tool decodes the audio track in your browser and gives you a downloadable audio file.

Question 2

Which video formats are supported?

Accepted Answer

Any video format your browser can play — typically MP4, WebM, MOV, M4V, OGV and (in some browsers) MKV and AVI. If the video plays, the audio can be extracted.

Question 3

Does it really output MP3?

Accepted Answer

Browsers cannot natively encode MP3. The tool outputs WAV (lossless, universal) or WebM/OGG (Opus/Vorbis, lossy, small). Most modern players and editors accept all of these; you can rename Opus to mp3 if your player supports it.

Question 4

Is my video uploaded anywhere?

Accepted Answer

No. The video is decoded locally in your browser using the HTML5 video and Web Audio APIs. Nothing is uploaded to any server.
