Audio Compressor

Free Online Audio Compressor

Audio Compressor reduces the file size of your audio by re-encoding it to MP3 at a bitrate and sample rate you choose. Perfect for fitting audio into email attachments, messaging apps, or storage limits.

How It Works

-

Lossy MP3 compression removes inaudible data to shrink the file. A 44 MB WAV can become a 4 MB MP3 at 128 kbps — roughly a 10x reduction with minimal quality loss for most uses. Higher bitrates (256–320 kbps) preserve more detail for music. Everything runs in your browser via the Web Audio API and a JavaScript MP3 encoder — nothing is uploaded.

Lossy MP3 compression removes inaudible data to shrink the file. A 44 MB WAV can become a 4 MB MP3 at 128 kbps — roughly a 10x reduction with minimal quality loss for most uses. Higher bitrates (256–320 kbps) preserve more detail for music. Everything runs in your browser, with the LAME MP3 encoder compiled to WebAssembly — nothing is uploaded.

Choosing the Right Bitrate

64 kbps — voice recordings and podcasts (smallest files). 128 kbps — general purpose, good quality for most uses. 192 kbps — high quality for music. 320 kbps — maximum quality, indistinguishable from uncompressed for most listeners. Lowering the sample rate to 22 kHz or 16 kHz shrinks speech files further.
