M4A is an MP4 container that usually holds AAC audio inside. Some hardware players, DAWs and embedded devices want the bare AAC stream instead of the container, and converting gives you exactly that without re-encoding damage.
Drop your M4A file above and Morphix decodes it locally, then re-encodes it as AAC 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.
