How to compress audio online

The CompressorBR workflow keeps every MP3/WAV on the browser, so legal and confidential audio never leaves your device.

  1. Head over to the home page and drop your audio file.
  2. Pick the 128 kbps or 192 kbps preset depending on the target platform.
  3. Wait for the progress bar to hit 100% and download the new file.

Tip: very large recordings may consume plenty of RAM; if the browser becomes sluggish, run the workflow in smaller chunks or a desktop-class device.
