Fade Audio adds a smooth fade-in at the start and fade-out at the end of a track, so it eases in and out instead of starting or stopping abruptly. Set each fade's length and export a more polished clip, processed entirely in your browser.
Drop your file in; its length is detected for placing the fades.
Choose how many seconds the fade-in and fade-out should each last.
Export to apply the fades and save the smoothed track.
Yes — set one fade to zero seconds to apply just the other.
One to three seconds suits most music; shorter fades work well for speech and effects.
No — the fades are applied within the existing audio, so the duration stays the same.
No. This tool runs entirely in your browser — your file is processed on your own device and never leaves it. The only network request is an anonymous usage counter.
