This free online converter turns WEBM videos into WMV files in your browser, with no software to install and no watermark. When the video and audio inside your WEBM file can be placed in WMV as they are, the streams are copied without re-encoding, which is faster and keeps the original quality. Otherwise the video is re-encoded as Windows Media Video 8 with Windows Media Audio 2.
