FLAC is the standard for music libraries because it compresses without discarding data. Converting M4A to FLAC gives you a consistent, future-proof archive format across your whole collection.
Drop your M4A file above and Morphix decodes it locally, then re-encodes it as FLAC 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.
