If a conversion is needed, then HandBrake is a free and open-source tool for converting WMV files.

However, keep in mind that the conversion process might cause picture quality to decrease. WMV is also easy to convert to other video file types. VLC media player is another reliable option, which can play multimedia files across several platforms. Microsoft developed WMV and ASF, and many videos online today are WMV files. The best player for opening a WMV file is Microsoft Windows Media Player.

Most media players can open and read WMV (and ASF) files. A digital container format, called Advanced Systems Format (ASF), often encapsulates WMV files. It compresses the file size with a codec resulting in an easy-to-manage file that maintains the quality of the video. Windows Media Video (WMV) is a common and widely supported video format.
