Why convert MOV to MKV?

MKV handles multiple audio tracks, subtitles and chapters better than MOV, which is why media servers like Plex and Jellyfin prefer it. This tool re-encodes locally so your library stays consistent.

How it works

Drop your MOV file above and Morphix decodes it locally, then re-encodes it as MKV 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.
