How to shrink audio:

  1. Select any audio file (MP3, WAV, OGG, M4A, FLAC, etc.)
  2. Choose a shrink preset or use custom settings in the panel on the right:
    • Maximum Shrink – 32 kbps, 16 kHz, mono (tiny files, speech only)
    • Medium Shrink – 64 kbps, 22 kHz, mono (good for podcasts)
    • Light Shrink – 96 kbps, 44 kHz, stereo (acceptable for music)
    • Custom – set your own bitrate, sample rate, channels
  3. Click "Shrink & Export MP3" – the file will be re‑encoded to a much smaller MP3
  4. Download the tiny audio file and see the amazing size reduction
