Convert M4R to WMV online, for free.
Apple iPhone Ringtone (M4R) is the file format Apple uses to store ringtones on iPhones. The maximum length of an M4R file is 40 seconds. The only difference between M4R and MPEG 4 Audio (M4A) is the file extension, which lets an iPhone know M4R is a ringtone instead of a song.
As a format deployed by Apple for iPhone ringtones, M4R files open on iTunes by default.
Alternatively, Apple iOS is another good choice for opening M4R files. To create a custom ringtone, simply save an M4A file as an M4R file, and then import it into the iPhone.

Windows Media Video (WMV) is a common and widely supported video format. It compresses the file size with a codec resulting in an easy-to-manage file that maintains the quality of the video. A digital container format, called Advanced Systems Format (ASF), often encapsulates WMV files.
Most media players can open and read WMV (and ASF) files. The best player for opening a WMV file is Microsoft Windows Media Player. Microsoft developed WMV and ASF, and many videos online today are WMV files. VLC media player is another reliable option, which can play multimedia files across several platforms.
WMV is also easy to convert to other video file types. However, keep in mind that the conversion process might cause picture quality to decrease. If a conversion is needed, then HandBrake is a free and open-source tool for converting WMV files.
