Supported: MP4, MOV, MKV, WEBM, AVI · Processed entirely in your browser
Converted entirely in your browser using a WebAssembly build of FFmpeg — your file is never uploaded anywhere. Larger files take longer and use more memory.
Extract Audio from Video pulls the audio track out of any supported video file entirely in your browser — the tool to reach for whenever a webinar, lecture, interview or clip is really only useful for its sound.
What kinds of video files does this actually work with?
It's built to handle the common video containers people actually have on hand — MP4, MOV, AVI, WebM, MKV and others — pulling out just the audio track and saving it as a standalone audio file, without needing to know or care which specific format the video happens to be in.
Does extracting the audio lose any quality?
It depends on the output format you choose — extracting to a compressed format like MP3 involves some quality loss compared to the original, while an uncompressed format like WAV preserves the audio essentially unchanged, at the cost of a much larger file.
Is this private, and does the video get uploaded anywhere?
No — the entire extraction happens directly in your browser, so the video file is never uploaded to a server; it's also completely free, with no sign-up and no limit on how many files you convert.
Why turn a video into audio-only in the first place — isn't that what podcasts already are?
It essentially is, and the format has a specific birthday: journalist Ben Hammersley coined the word "podcast" — a blend of "iPod" and "broadcast" — in a February 2004 article for The Guardian, needing a quick label for a new kind of downloadable audio show while padding out the piece to fit the page on deadline. The technology behind it came from former MTV VJ Adam Curry and software developer Dave Winer, who built a program called iPodder that let people subscribe to audio feeds and automatically download new episodes — the same basic pattern every podcast app still uses today. Turning a recorded video — a webinar, an interview, a lecture — into standalone audio is exactly the same instinct that made podcasting popular in the first place: sometimes all you actually wanted was the sound.
