Extract audio
Pull the soundtrack out as MP3, WAV, or AAC.
This runs in your browser. Nothing is uploaded. Longer clips take longer here than they would on a fast server — that is the trade-off for not sending the file.
About Extract audio
Pulls the audio track out of a video as MP3, WAV, or AAC in your browser, without uploading the clip to an extractor.
Extracting a lecture soundtrack so you can listen on a walk should not require handing the MP4 to a site that also sells VPNs. This page runs FFmpeg with `-vn` and writes MP3 (lame), WAV (pcm), or AAC in an M4A wrapper. The picture is discarded. The encoder is the same ~30 MB wasm core the other video tools load.
WAV is huge and lossless-ish for the decode you get. MP3 at 192 kbps is the default people actually want. AAC is there for Apple-shaped workflows. If the video has no audio stream, FFmpeg errors and the page shows that rather than a silent file that looks successful.
There is a twin page under Audio → from video. Same command, different URL, so people searching either way land on a tool that does the job. I am not maintaining two encoders.
If the clip is an hour long, extracting still means decoding the whole container in the tab. Trim first when you only wanted the last answer in the meeting.

Common questions
Is this the same as the Audio from video page?
Yes. Same FFmpeg arguments, same formats. Use whichever URL you remember. Related links go both ways so you are not hunting.
Can I extract only a range of the soundtrack?
Trim the video first, then extract. This page is `-vn` on the whole file. Splitting the two steps keeps each tool’s controls short.
What happens with multiple audio tracks?
FFmpeg’s default mapping wins, usually the first stream. There is no track picker. If you need stream 1 instead of stream 0, a desktop build of FFmpeg with `-map` is the honest tool.

Why this one doesn't upload your file
There is no server to upload to. This page is a static file, and the work happens in your browser using the same graphics and WebAssembly code that renders every other site you visit. Your file is read from disk into memory, processed, and handed back as a download. Once the page has loaded you can disconnect from the network entirely and it keeps working. The longer explanation
