Frequently asked questions

What kind of noise does it remove?

It targets steady background noise under speech, such as fans, air conditioning, keyboard hum and street noise. It uses RNNoise, a small neural network built for voice calls. Loud sudden sounds or other voices in the background may remain.

Can I use it on music?

It is designed for speech and outputs mono audio, so music may sound thin or have parts removed. For music, use a tool made for it.

Are my files uploaded anywhere?

No. Remove Background Noise runs entirely in your browser. Your files are processed on your device and are never sent to a server.

Is there a file size limit?

No fixed limit. The only limit is your device's memory. Very large files work best in a desktop browser.

Is Remove Background Noise really free?

Yes. There's no account and no watermark. A short optional ad, or a 20-second wait, unlocks each download. That's how we keep it free.

Does it work offline?

Once the page has loaded, processing happens locally, so it keeps working even if your connection drops.
