Extract the Audio Track From a Video

Save a video's sound as MP3, WAV or the original untouched track. Runs entirely in your browser, with nothing uploaded and no length limit.

Runs entirely in your browser — nothing is uploaded

Three ways to take the sound out

They are genuinely different operations rather than three labels for one, and the right choice depends on what happens to the audio next.

  • MP3 re-encodes the audio into the format everything plays. Right for listening, sending and archiving.
  • WAV decodes it and stores it uncompressed. Right when the audio is going into an editor, because further edits and exports will not stack another generation of lossy compression on top.
  • Original track lifts the existing audio stream out of the container without decoding anything. A perfect copy, and close to instant.

Why copying is usually the best answer

The audio inside a video has already been compressed, almost always as AAC. Converting it to MP3 compresses it a second time, and a second pass can only ever remove more — it cannot restore what the first one discarded. Copying avoids that entirely.

The trade is that you get the format that was in there, saved as.m4a, rather than one you chose. That plays in every browser, on every phone and in every modern player, but a few older devices and some car stereos still want an MP3.

When a video has no audio at all

Screen recordings made without a microphone, clips exported from some editing software, and video shot with the microphone disabled frequently carry no audio track. There is nothing to extract in that case, and the tool reports it rather than handing you a silent file that looks like it worked.

Nothing is uploaded

The decoding runs inside your browser through a WebAssembly build of ffmpeg, so your video is read from your disk and worked on in memory on your own machine. That matters more than usual here: the recordings people want the audio from are often meetings, interviews and lectures they would rather not hand to a stranger.

Frequently asked questions

How is this different from Video to MP3?

Video to MP3 always produces an MP3. This offers WAV when you need uncompressed audio for editing, and a copy mode that takes the existing audio track out of the container without re-encoding it at all.

What does copy mode do?

It lifts the audio stream out of the video file byte for byte, with no decoding and no re-encoding, so the result is a perfect copy of what was already in there. It is also close to instant, because nothing is being computed. The catch is that you get whatever format the video used — usually AAC, saved as .m4a — rather than a format you chose.

When should I use WAV?

When the audio is going into an editor for further work. WAV is uncompressed, so each subsequent edit and export does not stack another generation of lossy compression on top. It is a poor choice for listening or sending, being roughly ten times the size of an equivalent MP3.

Does a video always have audio?

No. Screen recordings made without a microphone, and clips exported from some editing apps, carry no audio track at all. When that is the case the tool says so rather than handing you a silent file.
