OPUS is great for chat apps but won't open in most audio editors, players, or DAWs. MP3 is the safe lingua franca.
Drop your OPUS 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.
