1. Can iPhone Play MKV Files?
iPhone supports playing MKV files, but only when the files are JPEG (M-JPEG)-encoded MKV videos (up to 1280×720, 30 fps, and raw audio). So if your MKV file is encoded with the above codec, it will play on your iPhone; otherwise, playback will fail.
2. How to Play MKV on iPhone Without Converting?

One decent app that can be downloaded from the App Store is VLC Media Player. Developed by the VideoLAN project, the app has a good rating and supports playing videos in a wide range of formats, including MKV, FLV, AVI, MOV, and many others.
