Frequently asked questions

What does the Fade Audio tool do?

Add a fade-in and fade-out. 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.
