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
