M4A is an MP4 container that hides AAC audio inside, which some hardware players and audio tools refuse to open. AIFF is the lossless format Logic, Final Cut and older Mac audio tools expect, with better metadata handling than WAV, so converting turns a file you are stuck with into one you can actually use. Morphix does the whole M4A → AIFF conversion locally with WebAssembly, so even sensitive material never leaves your device.
Drop your M4A file above and Morphix decodes it locally, then re-encodes it as AIFF using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Batch as many files as your machine can handle.
