Extract the audio from a video

Drop a video file, choose between MP3 and the lossless original track (.m4a), download. The video is read in your browser and its audio track written out right there — nothing is uploaded, which is also why there is no server-side size limit. MP4, MOV, WebM and MKV are supported.

Lossless copy or MP3 — which is better?

Copying losslessly takes the existing audio track out of the video unchanged and puts it into an M4A container. Nothing is recalculated: no quality loss, and the job is many times faster because the data is only repackaged instead of re-encoded. MP3 re-encodes the track — a second lossy compression, but the result plays on practically any device, including an old car stereo.

When is the lossless copy not possible?

Only when the codec cannot live inside an MP4/M4A container. AAC, MP3, Opus, FLAC and AC-3 fit — which covers virtually every video from a phone or camera, as those almost always use AAC. Vorbis (in older WebM files) does not fit; in that case the tool re-encodes and tells you so in the result, instead of claiming a lossless outcome.

Can I download YouTube videos with this?

No, and that is a deliberate decision. This tool only processes video files that are already on your device — your own recordings, footage you made yourself, or material you hold the rights to. Downloads from streaming platforms generally violate their terms of use and, depending on the source, copyright, so we do not offer them.

Honest limits

  • Audio only. The video track is discarded — that is the point, but there is no way back into the same video.
  • Up to 3 hours. The process streams and therefore needs little memory, but very long recordings take correspondingly longer.
  • Subtitles and multiple audio tracks: the primary audio track is used. A video with several language versions gives you the main track, not all of them.
  • Metadata such as titles or chapter markers is not reliably carried over into the output file.

Frequently asked questions

Is my video uploaded?

No. The video is read and its audio track written out in your browser. Nothing is transferred, which also means there is no file size limit from a server — only your device's memory.

Lossless copy or MP3 — what is the difference?

The lossless copy takes the existing audio track out of the video and puts it into an M4A container without touching the data, so there is zero quality loss and it is very fast. MP3 re-encodes the track: a second lossy compression, but the result plays on practically every device and in every car radio.

When is the lossless copy not possible?

Only when the codec cannot live in an MP4/M4A container — AAC, MP3, Opus, FLAC and AC-3 can, Vorbis (in older WebM files) cannot. In that case the tool re-encodes and says so instead of silently claiming a lossless result.

Can I download the audio of a YouTube video with this?

No, and that is deliberate. The tool only processes video files that are already on your device. Downloading from streaming platforms usually violates their terms of use and, depending on the source, copyright — so we do not offer it.

Which video formats work?

MP4, MOV, WebM and MKV — the containers every phone and camera produces. The video track is discarded, only the audio is written out, and the process streams instead of loading the whole video into memory.
