Another option is to convert to WMV for free. Try the VLC media player – it’s a freeware app that lets you not only play media files but also convert them to different formats. However, the program has a few drawbacks – videos are processed rather slowly, and the app can’t handle very large files.
Download the VLC media player
Download and run the installation file, follow the on-screen instructions, and launch the program. Click Media in the upper-left corner and select the Convert / Save option. In the new dialog window, hit Add to upload the files you want to convert. Then click the Convert / Save in the lower part of the window. In the Profile section, open the list of formats and choose Video – WMV + WMA (ASF). Next, click Browse to pick the destination folder and rename the file, changing the extension to .wmv. Click Save. Now hit Start to launch the conversion.
