How to use the Audio Fade In / Fade Out

  4. Download the faded track.

Good fade lengths

  • 1–2 seconds: removes clicks and sudden starts.
  • 3–5 seconds: natural ending for a song or podcast.
  • 8–10 seconds: slow, radio-style fade out.

Good to know

Fades use a smooth curve rather than a straight line, which sounds more natural to the ear. Set either fade to 0 to skip it.

Frequently asked questions

Can I fade a section in the middle?

Cut that section with the MP3 Cutter first, then add fades to it.

How much does the Audio Fade In / Fade Out cost?

Nothing. It is free with no registration, no watermark and no limit on how many files you convert.

Is my file uploaded to a server?

No. The converter runs inside your browser using WebAssembly, so your file is processed on your own device and never sent to us or anyone else.

Can I use it on my phone?

Yes. Open the page in your phone's browser and choose a file. Phones have less memory than computers, so very large files are better converted on a laptop or desktop.
