Convert RM to MKV online, for free.
RealMedia (RM) is a multimedia container format that is proprietary to RealNetworks. RealNetworks designed RM to stream content over the Internet. RM compresses video with a RealVideo codec and audio with a RealAudio codec.
As a proprietary format, an RM file opens by default in RealPlayer, which RealNetworks developed. If RealPlayer is missing, then download it here.
Other programs that can open an RM file include VLC media player, MPlayer, and CrystalPlayer. For mobile, on Apple iOS, try OPlayer HD, and VLC media player for Android.

Matroska (MKV) is a free, open-source, container standard that can hold an unlimited amount of audiovisual and multimedia files in a single file format. Since it is open source, a user can customize it with open-source software. The name derives from “Matryoshka” dolls, which is a famous type of Russian handicraft that consists of a set of wooden dolls of decreasing size nested one inside another.
The best way to open an MKV file is to use VLC media player. This media player is compatible with all operating systems and platforms. This is important because MKV is not an industry standard, which means that other media players might not support it.
Additionally, MKV does not use codecs to compress file size, which means the file can be quite large. Therefore, another option for opening an MKV file is to download the appropriate codecs that are compatible with the selected media player. To accomplish this, download the Combined Community Codec Pack (CCCP) from a trusted site, such as Ninite.
