About Audio Compressor
About the Audio Compressor
The Audio Compressor shrinks an audio file's size by re-encoding it more efficiently — handy for email, faster uploads and lighter podcast feeds. You trade a little fidelity for a smaller file.
(For evening out loud and quiet levels, that is the Dynamic Range Compressor — this tool is about file size.)
How to use the Audio Compressor
Select the audio file you want to shrink.
Pick a compression level: light for best quality, medium for balance, heavy for a small file, or maximum for voice-only.
Run it and download the smaller file. To hit an exact kbps figure instead, use the Audio Bitrate Converter.
Frequently Asked Questions
It depends on the source and target bitrate — dropping a high-bitrate file to 128 kbps can cut size by more than half with little audible change for voice.
Lossy compression discards some detail, but at sensible bitrates it's inaudible for spoken word. Keep your original as a master.
