Desktop converters require downloads. Online converters upload your files to unknown servers. AudioUtils does neither. It runs WebAssembly in your browser tab.

The conversion is fast. A typical 5-minute audio file converts in under 3 seconds. No progress bars that stall at 99%.

WAV is lossless. Converting to M4A reduces file size at the cost of some audio data. Use a high bitrate to minimize loss. Works on Chrome, Firefox, Safari, and Edge. Any device, any OS.
