Wondering why videos won't play on your iPhone? Chances are that your device doesn't support the file format of the video you want to watch. By default, your iPhone works only with .m4v, .mp4, and .mov file formats for videos. But if you've just downloaded a video from the web, it's likely saved in either .avi or .mkv. The built-in apps like Photos and Files just won't play such a video.
Don't worry, our free Documents app can play all your favorite videos. Documents is the best iPhone video player app, file manager, and downloader, which supports the playback of numerous file formats for your movies, tv shows, and other videos: .3gp, .l16, .m3u, .m4v, .mm, .mov, .mp4, .scm, .avi, .mkv, .flv.
