FAQ

M4A to WAV, answered.

Will I lose quality converting M4A to WAV?

No. WAV is a lossless format, so no image or audio detail is discarded in the conversion.

Is M4A the same as MP3?

No. M4A (AAC) is Apple's format and slightly more efficient, but MP3 is more universally supported across devices and apps.

Why are WAV files so big?

WAV stores audio uncompressed for maximum fidelity, so files are large. Converting to MP3 shrinks them dramatically with little audible difference.

Do my files get uploaded when I convert M4A to WAV?

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.

Can I convert several M4A files to WAV at once?

Yes. Drop in a batch of M4A files and PrivateRemix converts them all locally, saving each new WAV next to its original.
