An audio extractor pulls the soundtrack out of a video and saves it as a standalone audio file. The video stream is discarded and only the sound is written out, as MP3, AAC, FLAC or WAV. Extraction runs server-side with ffmpeg entirely in memory: the upload is never written to disk and nothing is left after the response is sent.
What Extracting Audio Actually Does
A video file holds separate streams - the picture, the sound, and the timing that keeps them aligned. Extracting reads the audio stream, re-encodes it into the format you choose, and writes it out on its own. The video is simply dropped.
This is the mirror image of muting. Where the mute video tool keeps the picture and discards the sound, an audio extractor keeps the sound and discards the picture. Running the same file through both leaves you with a silent video and its soundtrack as two separate files.
Why Extract Audio from a Video
- Listening without watching: a lecture, interview, podcast recording or conference talk works fine as audio, and the file is a fraction of the size.
- Music from a recording: pulling a track out of a video you own so it can go into a music library or playlist.
- Transcription: most speech-to-text services take audio rather than video, and uploading a smaller file is faster.
- Reusing a soundtrack: lifting narration, an interview clip or sound effects to use in another project.
- Storage: when only the sound matters, keeping the audio and deleting the video saves a great deal of space.
How This Audio Extractor Works
Drop a single video onto the upload card or click to browse. The clip appears in a preview player so you can confirm you have the right file. Pick an output from the Audio format dropdown - MP3 by default - and click "Extract audio". A progress bar tracks the job, and the extracted audio plays inline in an audio player with a download button when it finishes.
Files up to 100 MB are accepted, one at a time. MP4, MOV and WebM are all supported as input.
Choosing an Audio Format
- MP3: the default and the safe choice. Lossy, compact, and playable on absolutely everything - car stereos, old phones, anything with a speaker.
- AAC: lossy like MP3 but more efficient, so it sounds slightly better at the same file size. Well supported on modern devices and the standard inside Apple's ecosystem.
- FLAC: lossless and compressed. Preserves the source audio exactly at roughly half the size of WAV, which makes it the sensible choice for archiving or further editing.
- WAV: lossless and uncompressed. Largest by far, but the format some editing software and audio tools insist on.
Lossless Does Not Mean Better Than the Source
FLAC and WAV preserve whatever audio they are given, perfectly. What they cannot do is improve it. A video's audio track is normally already lossy - AAC in an MP4, Opus in a WebM - so extracting to FLAC gives you a lossless copy of a lossy original. The result is bit-perfect relative to what was in the video, not CD quality.
That is still a genuine reason to choose it. A lossless export adds no second generation of compression, so it is the right format if the audio is going into an editor or being archived. But if the goal is simply listening, MP3 or AAC produces a much smaller file that sounds the same, because the detail a lossless format would preserve was already discarded when the video was encoded.
Extracting, Muting and Converting
Three operations that are easy to confuse. Extracting keeps the sound and discards the video - this tool. Muting keeps the video and discards the sound, which the mute video tool does losslessly and almost instantly. Converting keeps both and changes the container or codec, which the video converter handles between MP4, MOV, WebM and GIF.
If the section you want is only part of a longer recording, trimming the video first means extracting just that portion rather than the whole thing - and it will bring an oversized file under the upload limit at the same time.
FAQ
Upload the video, leave the Audio format dropdown on MP3 and click Extract audio. The video stream is discarded, the soundtrack is re-encoded as MP3 and the result is offered as a download. MP3 is the default because it plays on effectively every device ever made, from car stereos to old phones.
MP3 for listening and sharing - it is compact and plays everywhere. AAC if you want slightly better quality at the same size and your devices are modern. FLAC if the audio is going into an editor or an archive, since it is lossless and about half the size of WAV. WAV only when a specific piece of software demands uncompressed audio, because the files are large.
Not better than the source, no. A video's audio track is normally already lossy - AAC in an MP4, Opus in a WebM - so a lossless export gives you a perfect copy of a lossy original rather than CD quality. It is still worth choosing when the audio is heading into an editor or an archive, because it adds no second generation of compression. For plain listening, MP3 or AAC sounds the same and produces a far smaller file.
The most common reason is that the video has no audio track at all - screen recordings and clips that were muted earlier often do not. Rather than hand you a silent, empty file, the job is deliberately failed so the problem is obvious. Check whether the video actually plays sound before extracting. The other possibility is a file over the 100 MB limit, which is rejected at the upload step.
Not in one step - this tool extracts the entire soundtrack. To get a specific section, run the video through the video trimmer first to cut it down, then extract the audio from the trimmed clip. That has the useful side effect of bringing an oversized recording under the 100 MB upload limit.
They are opposites. Extracting keeps the sound and discards the picture, giving you an audio file. Muting keeps the picture and discards the sound, giving you a silent video. If you want both - the soundtrack on its own and a silent version of the clip - run the original file through each tool in turn.
MP4, MOV and WebM, up to 100 MB per file, one at a time. That covers phone recordings, screen captures and video downloaded from the web. Whatever the source container, the audio is re-encoded into the format you pick from the dropdown.
No. The file is sent to the server because extraction needs ffmpeg, but it is never written to disk. It is held in memory for the duration of the job, the audio file is returned to your browser, and the buffer is released as soon as the request completes. Nothing is stored, logged or cached. The preview you see beforehand is your own local file and is not uploaded until you press the button.
