PrivateRemix handles the M4A-to-WAV conversion in a couple of clicks, with the result saved right next to your original file.
Unlike free online converters, PrivateRemix has no server. Your M4A files stay on your Mac — no upload, no cloud, no account.
Drag a M4A file into PrivateRemix, or pick one from your Mac.
Select WAV from the formats PrivateRemix offers for your file.
The new WAV appears next to the original. Nothing leaves your Mac.

WAV stores audio uncompressed for maximum fidelity, so files are large. Converting to MP3 shrinks them dramatically with little audible difference.
No. PrivateRemix runs entirely on your Mac using its own processor. Your M4A files never leave the device — there is no server to upload to, and it works fully offline.
Yes. Drop in a batch of M4A files and PrivateRemix converts them all locally, saving each new WAV next to its original.
