MKV can hold multiple audio tracks, subtitles and chapters, which is exactly why phones and TVs choke on it. M4V is the Apple video extension iTunes, Apple TV and QuickTime treat as a first-class citizen, so converting turns a file you are stuck with into one you can actually use. Morphix runs the whole MKV → M4V conversion locally with WebAssembly, so even confidential material never leaves your device.
Drop your MKV file above and Morphix decodes it locally, then re-encodes it as M4V 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.
