FLAC sounds superb but eats storage and does not sync cleanly to iPhones. M4A with AAC keeps the listening experience close to the original at roughly a fifth of the size, and it drops straight into Apple Music and iOS.
Drop your FLAC 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.
