Why convert MKV to MP4?
MKV (Matroska) is a flexible open container, but phones, consoles, and smart TVs often refuse it. MP4 is the universal container — same video quality, accepted everywhere.
Multiple audio or subtitle tracks in the MKV are folded into a widely compatible MP4 so the file just plays, no extra software needed.
