There is no standard video file extension called .wfp . It is most likely a typo or an uncommon proprietary format. The closest common formats are .wmv (Windows Media Video) or .webm (web video). If your file is genuinely .wfp , it may be from a specific security camera or scientific instrument. In that case, online converters will likely fail, and you will need dedicated desktop software.

Online converters work perfectly for standard video formats. For a mysterious .wfp file, switch to desktop software like HandBrake or VLC (which can also convert).
