Compress Audio
Reduce audio file size.
Compress Audio
Choose one or more files. Compression runs locally in your browser with the FFmpeg WebAssembly engine — nothing is uploaded. Each card shows the original size, the new size, and how much was saved. If a file cannot be made smaller, the card says so honestly.
