Add a fade to audio

Ease in and out

A fade-in ramps the volume up from silence at the start; a fade-out ramps it down at the end — no more abrupt starts or hard cut-offs. Set each length independently.

Keeps your format

The faded audio is saved back in its own format (MP3, WAV, M4A…), or pick another in the convert step. Anonymous uploads are temporary and encrypted in transit.

Frequently asked questions

How do I fade audio in or out?

Upload your file — it's pre-set to a 2-second fade in and out. Adjust the Fade in (s) and Fade out (s) in the convert step and download.

Can I fade only one end?

Yes — set the other to 0. For example fade-in 3 and fade-out 0 ramps up the start but leaves the end as-is.

Is it free and private?

Yes — no account, over an encrypted connection, and anonymous files are temporary.
