What is Audio Compressor?

A browser-based audio compressor that reduces the file size of your audio files by re-encoding them at a lower bitrate. Supports MP3, WAV, OGG, and other common formats. All processing happens locally — your files never leave your device.

How to use

  1. Upload an audio file (MP3, WAV, OGG, FLAC, or AAC) by dragging it onto the drop zone or clicking to browse.
  2. Choose your target format and quality level. Lower bitrates mean smaller files but reduced audio quality — preview before committing.
  3. Click Compress to process the file, then download the compressed result. Compare file sizes to see how much space you saved.

Result

A podcaster has a 45MB WAV recording and needs to email it. They compress it to 128kbps MP3, reducing it to 4MB while maintaining clear speech quality.
