Add an audio fade-out to end any track smoothly
An audio fade-out lowers the volume gradually until the sound disappears, so a track ends gracefully instead of stopping dead. This free tool adds a fade-out to MP3, WAV, M4A, FLAC and Ogg files — at the very end, or starting from any point you choose, with everything after the fade trimmed away.
That second mode is what makes it useful beyond tidying endings: shorten a long song to the length of a video, end background music exactly when a presentation finishes, make a 30-second ringtone that fades instead of cutting off, or create a radio-style ending for a song with an abrupt finish. Choose from four fade curves and see the result on the waveform before you export.
Nothing is uploaded: decoding, fading and encoding all happen in your browser, using Mediabunny (MPL-2.0) and, when you save MP3 or FLAC, the LAME (LGPL) or libFLAC (BSD) encoder.
How to use the Audio Fade Out
- Drop an audio file on the box or click to choose it. Its format, duration, sample rate, channels and bitrate appear with a waveform.
- Choose At the end of the file, or From a point to fade out earlier.
- Pick a fade curve and set the Fade length — or drag the handles on the waveform. In point mode, type the time the fade starts.
- Keep Trim everything after the fade ticked to make the file end with the fade, and optionally set an End volume above 0 %.
- Choose the output format, press Apply fade-out, compare the two players and download.
Audio Fade Out features
Fade at the end or from any point
Fade the last few seconds, or start a fade anywhere and cut the rest — a song becomes exactly as long as you need.
Four curves, mirrored for endings
Linear, exponential (a natural decay), logarithmic (holds, then drops) and S-curve, each shown as an icon and drawn over the waveform.
Waveform preview with zoom
The faded audio is drawn at its new level over a faint copy of the original, so you can see where it becomes inaudible.
Fade down to a level
Set an end volume of 10–95 % to dip the music under something else instead of silencing it.
Precise times
Type the start in minutes, seconds and hundredths, or drag the handles with a mouse or a finger; the gain is computed for every sample.
Choosing a fade-out curve
For a fade-out the gain follows the mirror image of the fade-in curve: with progress x from 0 to 1, gain = curve(1 − x).
| Curve | Gain at 25 % / 50 % / 75 % of the fade | Character | Use it for |
|---|---|---|---|
| Linear | 0.75 / 0.50 / 0.25 | Steady in amplitude, so it seems to linger and then vanish suddenly | Short fades, speech |
| Exponential | 0.51 / 0.24 / 0.09 | Drops quickly, then a long quiet tail — like a natural decay | Classic song endings |
| Logarithmic | 0.89 / 0.74 / 0.51 | Stays loud, then falls away near the end | Fading under the next scene or cue |
| S-curve | 0.85 / 0.50 / 0.15 | Gentle at both ends | Ringtones and loops |
How long should a fade-out be?
- Songs: 5–10 seconds is a common choice; much shorter fades can sound like an abrupt edit.
- Background music in a video: start the fade 2–4 seconds before the video ends, using “From a point” with the trim option.
- Ringtones and alarms: 1–2 seconds, so the sound loops without a click.
- Voice recordings: 0.2–0.5 seconds after the last word removes room noise and breaths without clipping the speech.

Audio Fade Out FAQ
How do I add a fade-out to an MP3?
Drop the MP3 here, keep “At the end of the file”, set the length (try 5 seconds for a song), pick a curve and press Apply fade-out. Same as input keeps it an MP3.
Can I make a song shorter and fade it out?
Yes. Choose “From a point”, type the time the fade should start, set the length and keep “Trim everything after the fade” ticked. The new file ends when the fade does.
Is this audio fade-out tool free and safe?
Yes. It is free with no sign-up or watermark, and the audio is processed entirely in your browser — it is never uploaded.
Which curve sounds most natural?
For music, the exponential curve: it drops quickly and then trails off slowly, which our ears hear as an even fade. Linear fades tend to sound as if the music stops suddenly at the end.
Will the rest of the audio be re-encoded?
With MP3, M4A or Ogg output the whole file is re-encoded; choose a bitrate at least as high as the original. WAV and FLAC output are lossless.
Can I fade out to a lower volume instead of silence?
Yes. Set End volume to, say, 30 % and untick the trim option; the audio after the fade continues at that level.
