MKV is a powerful container but doesn't play in Quicktime, iOS, most browsers, or social uploaders. MP4 plays everywhere.
Drop your MKV file above and Morphix decodes it locally, then re-encodes it as MP4 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.
