Which output formats are available?

You can extract audio as MP3 (compressed, widely compatible) or WAV (lossless PCM, large file size). Use MP3 for sharing and streaming, WAV for further audio editing.

Which input video formats are supported?

ffmpeg.wasm supports MP4, WebM, MOV, AVI, MKV, and most other common video containers as input.

Does audio extraction re-encode the audio?

For MP3 output, yes — the audio is re-encoded. For WAV output from a video with PCM audio, the audio is extracted without re-encoding. In both cases the video track is discarded entirely.

What is the MP3 output bitrate?

MP3 is encoded at 192 kbps by default, which provides transparent quality for music and speech. This is not configurable in the current version.

Is my video uploaded during extraction?

No. ffmpeg.wasm processes your video entirely inside your browser. Nothing is transmitted to any server.

How fast is audio extraction?

WAV extraction is near-instant since it copies the audio stream. MP3 encoding requires re-encoding and takes a few seconds to a minute depending on video length.

What if the video has no audio track?

If there is no audio track in the video, ffmpeg will return an error. Use the Video Muter (which removes audio) or Frame Extractor for silent videos.

Can I use the extracted audio in a video editor?

Yes. Both MP3 and WAV are universally supported in all audio and video editing software including Adobe Premiere, Final Cut Pro, DaVinci Resolve, and Audacity.
