Opus is superb for voice and streaming, but many editors, players and upload forms still bounce a .opus file. FLAC is mathematically lossless yet roughly 40–50% smaller than raw PCM, and it is the standard for serious music archives, so converting turns a file you are stuck with into one you can actually use. Morphix does the whole OPUS → FLAC conversion locally with WebAssembly, so even sensitive material never leaves your device.
Drop your OPUS 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.
