Why convert M4A to WAV?

Transcription tools, samplers and audio editors like Audacity work best with raw PCM. Decoding an iPhone M4A memo to WAV gives you a clean, editable waveform with no further generation loss.

How it works

Drop your M4A file above and Morphix decodes it locally, then re-encodes it as WAV 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.
