Frequently asked questions
What does the Denoise Audio tool do?
Remove hiss, hum and background noise from a recording. It runs entirely client-side — nothing is uploaded to a server.
Is my file private?
Yes — processing happens locally in your browser tab using the Canvas API and WebAssembly, so your file never leaves your device.
Is there a cost or file size limit?
It's free with no upload limit. Processing time depends on your device and the size of your file rather than any imposed cap.
