M4A is Apple's container and isn't supported everywhere. MP3 plays on every device and platform without re-encoding hiccups.
Drop your M4A file above and Morphix decodes it locally, then re-encodes it as MP3 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.
