WebM is an audio-video format designed to provide a royalty-free, open video compression format for use with HTML5 video. WebM Video Converter is a freeware app for Windows which lets you convert the WebM into different formats. You can convert WebM video files to different video formats such as AVI, MP4, 3GP and others. You can also convert any video format back to WebM and extract audio MP3 from WebM using this free tool.
The interface is very simple, you need to add files to convert and then select the format to convert to. You can use the Tags button and set the Title, Album, Artist and other parameters as you want. By default the program will automatically fill the title tag and the artwork, taking a snapshot from the middle of video which can be seen in iTunes, Winamp, Windows Explorer.
