Audio Compressor

Reduce audio file size by lowering sample rate, converting to mono, and re-encoding — all in your browser.

Browser-based compression: Audio is decoded, resampled, optionally down-mixed to mono, then re-encoded as WAV (smaller sample rate / mono) or WebM/Opus (lossy compression). No files leave your device.
