Why convert WAV to M4A?

A minute of WAV is around 10 MB. M4A keeps near-identical quality at roughly a tenth of the size and plays natively on iPhone, Mac and every modern browser.

How it works

Drop your WAV file above and Morphix decodes it locally, then re-encodes it as M4A using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Batch as many files as your machine can handle.
