The Honest Note on Quality
M4A files hold AAC audio, which is lossy — it already discarded data to save space. Converting to WAV gives you a lossless, edit-ready container, but it can't restore detail the AAC compression removed. So an M4A-to-WAV file is bigger and editable, but sounds like the M4A source, not better. See is WAV lossless? Need the reverse? Use WAV to M4A.

How do I convert M4A to WAV?
Upload your .m4a or .aac file, keep WAV selected, then click Convert & Download. The WAV is created and downloaded automatically — no software or signup needed.
