Extract audio from video

How it works

1. 1

   Add your video

   Drop in the video whose soundtrack you want.

2. 2

   Choose a format

   MP3 for the smallest file, WAV for lossless, or AAC.

3. 3

   Extract and download

   Save the audio track. It downloads straight from your machine.

Pulling the audio out does not have to re-encode it

A video file is a container holding separate streams, and the soundtrack is already sitting inside it as a finished, independently encoded audio track. An MP4 usually carries AAC, a WebM usually carries Opus. Extracting that track can therefore be a copy rather than a conversion: the bytes are lifted out of the container and rewrapped, untouched.

That distinction is the whole game, because it is the difference between a perfect copy and a slightly worse one. Re-encoding an AAC track into an MP3 means decoding it back to raw audio and compressing it again with a different codec, and every lossy generation throws away a little more of what was there. The artifacts of the first encode become material the second encode faithfully preserves.

So when the audio can be copied out as is, that is what should happen, and it is close to instant because nothing has to be compressed. Ask for a format the source is not already in and a real re-encode is unavoidable, which is fine and often necessary, but it is worth knowing which one you are asking for.

Extract audio from video without uploading the video

The container is parsed and the audio stream lifted out on your own device. There is no upload, which matters more here than almost anywhere else on this site, because the videos people extract audio from are lectures, interviews, meetings, and recordings that were never meant to be handed to a third party in full just to retrieve the sound.

No size cap and no watermark, and since the video itself never travels, a two hour recording costs you processing time rather than an upload you have to babysit.

Once the audio is out, the audio trimmer will cut it down, the volume booster will fix a recording that came out too quiet, and the ringtone maker will turn a passage of it into something your phone will accept.

Why nothing uploads

Other tools send your video to their servers, which costs them money per file, so they add watermarks, cap file sizes, and make you sign up. This tool does the work right here in your browser using your own device. Your file is never uploaded, so there is no wait, no watermark, no size limit, and no account.

Questions

Does my video get uploaded?

No. Extraction happens in your browser; your file never leaves your device.

Which format should I choose?

MP3 is smallest and works everywhere. WAV is uncompressed and lossless (larger). AAC is efficient and modern.

Can I extract audio from any video?

Most common formats (MP4, WebM, MOV) work. If a file can't be read, convert it first, then extract.

Is it free?

Yes, no account, no trial, no watermark.
