The AAC audio in your M4A is decoded to plain PCM and written as a 16-bit WAV. Nothing further is lost; the WAV holds exactly what the decoder produced, in the most universally accepted audio format there is.
Expect a much larger file, since WAV stores samples uncompressed.
iPhone Voice Memos records M4A, and a surprising number of tools downstream want WAV: DAWs, transcription services, court and compliance systems, broadcast editors. This converter is the bridge, and because it runs locally, sensitive recordings stay on your machine.
For long-term storage rather than immediate editing, M4A to FLAC gives you the same safety at half the size.
