How to compress WAV to MP3:

  1. Select a WAV file (or any audio – MP3, FLAC, OGG, etc.)
  2. Adjust compression settings in the panel on the right:
    • Bitrate – lower = much smaller file (32–128 kbps)
    • Sample rate – 22050 Hz or 16000 Hz saves space
    • Channel mode – Mono reduces size by ~50%
  3. Click "Compress to MP3" – the file will be re‑encoded as MP3
  4. Download the compressed MP3 and enjoy up to 90% space savings
