About Extract Audio from Video (Video to MP3)

Extract Audio from Video pulls the audio track out of a video file and saves it as MP3, WAV, OGG or FLAC — all on your own device. It reads MP4, MOV, WebM and MKV (plain audio files work too), shows the clip's duration and codecs, and can grab just a section instead of the whole thing. Because nothing is uploaded, even large videos convert quickly and privately.

How to use Extract Audio from Video (Video to MP3)

  1. Drop a video into the tool or click to browse — MP4, MOV, WebM and MKV work, and so do plain audio files (up to 2 GB).
  2. Check the detected details: duration, size, audio codec and source appear as soon as the file is read.
  3. Pick an output format — MP3 for maximum compatibility (choose 128, 192 or 320 kbps), WAV or FLAC for lossless, OGG for small web-ready files.
  4. Optionally turn on 'Extract only a section' and set a start and end time in seconds or m:ss.
  5. Click Extract audio, watch the progress, preview the result in the built-in player, then save the file.

Frequently asked questions

Is my video uploaded to a server?
No. The audio is extracted entirely in your browser using its built-in media engine — the file never leaves your device. That's also why videos up to 2 GB are fine: there's no upload to wait for.
Which output format should I pick?
MP3 plays everywhere and is the safe default for sharing. Pick WAV or FLAC when you plan to edit the audio and want lossless quality, and OGG for small files at good quality on the web.
Will extracting lose audio quality?
MP3 and OGG are lossy, so the audio is re-encoded — at 320 kbps MP3 the difference is inaudible for most people. WAV and FLAC are lossless: they capture the decoded audio exactly, at the cost of larger files.
Does it work with iPhone videos (.MOV)?
Yes — MOV files from iPhones are supported as long as your browser can decode the codec. A current Chrome or Edge handles them best; if a file can't be read you get a clear error rather than a broken download.
Is there a length or file-size limit?
Files up to 2 GB are accepted, with no hard length limit — extraction is usually much faster than the clip's own duration because only the audio is processed. Extract just a section to go even faster.
