The private way to turn M4A / AAC into WAV
AAC audio in an MP4 container. Uncompressed PCM audio. With Morphr, the whole conversion runs inside your browser tab using Morphr's own engine — your file is never uploaded to a server, queued, or stored. That makes it a safe choice for personal photos, scanned documents and anything you'd rather not hand to a third party.
