Fade your audio in and out.
Drop a track and add a smooth fade in at the start, a fade out at the end, or both — no abrupt starts or hard stops. Everything runs in your browser; nothing is uploaded.
How to fade audio in and out
- Drop your file in. Choose or drag an MP3, M4A, WAV, OGG or FLAC — it loads in your browser and is never uploaded.
- Set the fades. Move the Fade in and Fade out sliders to the lengths you want; the panel shows the result. Leave either at 0 to fade just one side.
- Fade & download. Save the faded audio as MP3 or WAV.
Frequently asked questions (5)
Is Fade Audio free?
Yes — completely free, with no sign-up, no watermarks, and no limit on how many files you fade.
Do my files get uploaded?
No. The audio is decoded and faded entirely in your browser, so your file never leaves your device.
What's the difference between fade in and fade out?
Fade in ramps the volume up from silence at the start; fade out ramps it down to silence at the end. Set each length on its own slider, or leave one at 0 to fade only one side.
Which formats can I use?
Whatever your browser can decode — MP3 and WAV work everywhere, with M4A, OGG and FLAC where supported. The faded result is saved as MP3 or WAV.
Can I fade a long track?
Fades of up to 30 minutes of audio are supported in the browser. For a longer file, trim it in the Audio Cutter first, then fade.
