Where does the conversion happen?

In your browser. Our server only resolves the link and streams the video file through; the decoding and MP3 encoding both run on your own machine using the Web Audio API and an encoder loaded into a background worker. That means the audio is never processed on a server, and it is also why the tool works without us paying for any transcoding.

Why does it take a few seconds?

Because a real conversion is happening rather than a file being renamed. The video has to be downloaded, its audio track decoded to raw samples, and those samples encoded to MP3. A short clip takes a moment; a several-minute video takes proportionally longer. The work runs in a background worker so the page stays responsive.

What bitrate is the MP3?

It is encoded at 128 kbps in stereo, which is a sensible match for the audio X ships inside its videos. Encoding higher would inflate the file without recovering detail that was already lost in the original.

Why did my post fail?

The usual causes are a post with no video at all, a protected account, a deleted post, or a link to a profile rather than a specific post. Text-only and image-only posts have no audio to extract.

Is it free and does it need an account?

It is free with no account and no daily cap. A modest per-visitor rate limit applies to the link lookup, but the conversion itself runs on your device and is not limited at all.

Can I use the audio in my own videos?

Be careful. The soundtrack of a post is usually owned by whoever made it, or by a music rights holder, and extracting it does not grant you a licence. Personal listening is one thing; publishing the audio in your own work can trigger a copyright claim.
