W64 is Sony's Wave64 format for very long sessions, and most consumer players have never heard of it. M4A is the native Apple audio container, so the file drops straight into Music or a podcast editor with tags intact, so converting turns a file you are stuck with into one you can actually use. Morphix runs the whole W64 → M4A conversion locally with WebAssembly, so even confidential material never leaves your device.
Drop your W64 file above and Morphix decodes it locally, then re-encodes it as M4A 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.
