Audio extraction is a legitimate and common need — pulling the sound from a lecture you recorded, a talk you gave, a podcast you produced. The mechanics are simple. The question of where the file comes from is the part worth being careful about.

Extracting audio from a file you have

This is the straightforward case. Drop the video into our MP3 extractor and it strips the video stream and re-encodes the audio to MP3 at 192kbps, entirely inside your browser.

If the audio is going into an editor, a mastering chain, or a transcription tool, use the WAV converter instead. WAV is uncompressed, so it avoids a second lossy pass — at roughly ten times the file size.

A note on double compression

The audio inside a video file is already lossy — AAC in an MP4, Opus in a WEBM. Re-encoding it to MP3 compresses something that has already been compressed, and the artefacts of that second pass land on cymbals, sibilance and applause.

That is why 192kbps rather than 128kbps is the default here. At 128 the second pass becomes audible on most material; at 192 it generally does not. If your source is a lossless WAV or FLAC, 320kbps is worth choosing.

Getting your own YouTube audio

If the video is on your channel, download the original from YouTube Studio → Content → Download and extract the audio from that. You get the original upload rather than a capture of YouTube’s compressed stream, which means the audio has been through one fewer encode.

Music is the sharpest end of this question. It is the category rights holders pursue most actively, and it was the subject of Yout v. RIAA, where a stream-ripping operator failed to obtain a declaration that its tool was lawful.

More recently, in February 2026, a US federal court held in Cordova v. Huneault that YouTube’s rolling cipher is a technological access control under DMCA §1201 — so circumventing it can be unlawful independently of whether the copying itself would be fair use.

For music specifically, the supported route is a streaming service’s own offline mode. See is it legal to convert YouTube videos? for the full picture across the US, EU and UK.
