Free Online Audio Fade In / Out Tool

Add smooth fade-in and fade-out effects to your audio files online for free. Gradually increase volume at the start and/or decrease volume at the end of your track for professional-sounding transitions. Supports MP3, WAV, FLAC, M4A, OGG and other audio formats up to 200MB.

How to Add Fade Effects to Audio:

  1. Upload: Choose an audio file from your device or paste a URL.
  2. Set durations: Enter fade-in and/or fade-out duration in seconds. Set either to 0 to skip.
  3. Choose curve: Select a fade curve type (linear, logarithmic, exponential, etc.).
  4. Apply: Click "Apply fade!" and download the processed file.

Fade Curve Types

  • Linear: Constant rate of change — the simplest and most common fade.
  • Logarithmic: Matches how humans perceive loudness — sounds more natural for music.
  • Exponential: Fast initial change that slows down — dramatic fade effect.
  • Quarter/Half sine: Smooth S-curve transitions — gentle and musical.
  • Parabola/Quadratic: Accelerating or decelerating curves for different creative effects.
