AIFF stores uncompressed PCM, so an album can eat several gigabytes on disk. M4A is the native Apple audio container, so the file drops straight into Music, Voice Memos or a podcast editor with tags intact, so converting turns a file you are stuck with into one you can actually use. Morphix does the whole AIFF → M4A conversion locally with WebAssembly, so even sensitive material never leaves your device.
Drop your AIFF 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.
