Volume Booster

Increase audio loudness by up to 5x – export as MP3 or WAV

Drag & drop an audio file or click to browse

How to boost volume:

  1. Select an audio file (MP3, WAV, OGG, M4A, FLAC, etc.)
  2. Adjust the gain slider in the settings panel (right) – values above 1.0 increase loudness
  3. Use "Preview with Gain" to hear the effect (no file saved)
  4. Choose output format (MP3 recommended) and bitrate
  5. Click "Boost & Export" – the boosted file will be created locally
  6. Download the result and enjoy louder audio

All processing happens in your browser – files never leave your device. High gain may cause clipping (distortion).
