How to Play MKV on iPhone with/without Converting

By Cecilia Hwung | Last Update:

MKV is a multimedia container often used to store high-definition online videos and digital copies of DVD or Blu-ray movies. Although MKV is compatible with many players and devices, it's a little tricky to watch MKV on iPhone and iPad. So we are here to reveal everything about MKV files on iPhone and show you how to play MKV on iPhone with or without converting. Let's begin.

Can iPhone Play MKV

iPhone can't play MKV files natively, nor can iPad, Mac, and others in the Apple ecosystem. When you tap on the MKV file, iPhone won't send you any error message for the playback failure. It only shows the filename, media format (Matroska), and file size.

An added format support is a win, but why does Apple not support MKV?

MKV is a format container that can work with too many codecs of video, audio, images, and subtitles streams within it. The diversity of MKV codecs might lead to copy-right issues and heavy transcoding tasks. Therefore, Apple doesn't and won't launch native support for MKV files.
