How it works
This pulls the audio track out of a video and writes it as a standalone file, in your browser. The video stream is discarded with -vn and only the audio is encoded.
You are re-encoding, not extracting a copy, so there is one generation of loss on the lossy formats. For speech that is inaudible. If it matters, take WAV or FLAC and accept the size.

More detail
The output formats
- MP3, encoded with
libmp3lameat-q:a 2. That is variable bitrate averaging roughly 190k, which is a better quality-per-byte trade than a fixed 192k. The safe default if you are unsure. - WAV, uncompressed 16-bit PCM. Lossless relative to what the decoder produced, and very large - roughly 10 MB per minute in stereo. Use it when something downstream needs raw audio.
- OGG, Vorbis at
-q:a 5. Comparable quality to the MP3 setting at a slightly smaller size, if the destination supports it. - FLAC, lossless and compressed. About half the size of WAV with identical audio. The right pick for archiving.
- AAC at a fixed 192k. Better than MP3 at the same bitrate and what you want for anything going back into an Apple ecosystem or another video.
Things worth knowing
The audio you get is bounded by what was in the video. Extracting to FLAC from a video whose audio was already a 128k AAC gives you a lossless copy of a lossy source. It will not sound better than the original, it will just be bigger.
Everything runs in the browser through ffmpeg compiled to WebAssembly, so nothing is uploaded. The core is about 25 MB, fetched once per session. Input is capped at 500 MB.
A video with no audio track produces nothing useful. If the extraction fails immediately, check that the source actually has sound.
Questions
Is my video uploaded?
No. The extraction runs in your browser. The only network request is the one-time fetch of the ffmpeg core from a CDN.
Which format should I pick?
MP3 for anything you will just listen to or send someone. FLAC if you are keeping it and want no further loss. WAV only if a specific tool demands raw PCM, because it is by far the largest.
Will extracting to FLAC improve the quality?
No. Lossless encoding preserves exactly what it was given. If the video's audio was compressed, the FLAC is a perfect copy of that compressed audio, at several times the file size and no better sounding.
Can I extract only part of the video?
Not here. Trim the video first with the Video Trimmer, then extract from the shortened clip.
