How to Compress Audio Files?

Whether you are sharing a recorded lecture, optimizing a podcast for streaming, or sending a demo track via email, large audio files can be a headache. Uncompressed formats like WAV can take up massive amounts of storage space.

Our Audio Compressor fixes this by reducing the bitrate of your audio file:

  • High Quality (192 kbps): Best for music tracks where you want to preserve the rich frequencies. Minimal size reduction.
  • Standard Quality (128 kbps): The golden standard for MP3s. Offers a great balance between decent sound and small file size.
  • Maximum Compression (64 kbps): Ideal for voice recordings, lectures, and audiobooks where crystal-clear high notes aren't necessary.
