AC3 is a cinema surround codec pulled from DVDs and broadcasts, and most software players downmix or refuse it. M4B is the audiobook format Apple Books and podcast apps bookmark, resume and chapter properly, so converting turns a file you are stuck with into one you can actually use. Morphix runs the whole AC3 → M4B conversion locally with WebAssembly, so even confidential material never leaves your device.
Drop your AC3 file above and Morphix decodes it locally, then re-encodes it as M4B 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.
