Reduce WAV file sizes by lowering sample rate, bit depth, and channels. Choose from 3 compression levels for the right balance.

What Can You Do With Our WAV Compressor?

Our free online WAV compressor reduces uncompressed audio file sizes by adjusting sample rate, bit depth, and channels — keeping the WAV format intact for compatibility.

  • Low compression: keeps original sample rate with 16-bit audio — minimal quality loss, modest size reduction
  • Medium compression: 22050 Hz sample rate, 16-bit — good balance of quality and file size
  • Strong compression: 11025 Hz, 8-bit mono — maximum size reduction for voice recordings and non-critical audio
  • Batch compress up to 10 WAV files at once with detailed before/after size comparison
  • Output stays in WAV format — no format conversion, full compatibility with all audio tools
