MP4 is the safest video container, which also means it is the one everybody already has and nobody optimises. 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 MP4 → FLAC conversion locally with WebAssembly, so even sensitive material never leaves your device.
Drop your MP4 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.
