Take the soundtrack out of a video and keep it as its own file. The audio already exists inside the video, encoded, so lifting it out is a copy rather than a conversion: instant, and identical to what was in there. WAV is offered as well for older software that will not open an M4A. The video is never uploaded.
1 · Your video
2 · What to save it as
M4A is a copy of the sound already in the video, so it is instant and loses nothing. WAV is decoded and rewritten uncompressed: far larger, and no better, but older software will open it.
Frequently asked questions
Is my video uploaded anywhere?
No. Your browser reads the file and writes the audio out, all locally. The site’s security policy sets connect-src ‘none’, so the browser blocks network requests from these pages, meaning the video could not be sent even if the code tried.
Why is there no MP3 option?
Because the browser will not encode one. It was asked directly: it offers AAC and Opus and refuses MP3. Adding it would mean shipping an encoder, for a format whose advantage over M4A is that people have heard of it rather than anything about the sound or where it plays. An M4A opens on phones, computers and every browser.
Does extracting lose quality?
Not with M4A. The soundtrack is already sitting inside the video as encoded audio, and this copies it into a container of its own without decoding it, so the result is the same audio. WAV does decode it, which does not improve anything: the source was already compressed, and a copy cannot be more faithful than the original.
Then why would I pick WAV?
For software that will not open an M4A, which in practice means older audio editors. It is several times the size for the same sound, so it is the right answer only when something downstream insists.
Which files does it take?
MP4 and MOV, which is what phones, cameras and screen recorders produce. AVI and MKV use a different container and are not read.
