WebM is a rather new video file format that was initially released only 6 years ago and has continuously grown in popularity ever since, as it's a format intended to be used with HTML5 videos, therefore it's royalty-free and its development is sponsored by Google.
Free WebM Encoder is a very simple tool that lets you quickly and easily batch convert video files to the WebM format. It can output only to WebM files and the advanced parameters of the final files, like bit rate or quality level, cannot be customized. As for the input files, only seven formats are supported: AVI, MP4, M4V, FLV, MOV, 3GP, and WMV. Anyway, it can batch convert multiple files at the same time, and this can save you a lot of precious time.
Another cool thing about Free WebM Encoder is the fact that it's really easy to use. Its neat and straightforward interface can be used with ease even by complete beginners. Furthermore, the conversion speed is pretty satisfactory, even when it comes to large files.
Anyway, this tool is made to be very simple and straightforward, therefore it comes with no advanced settings or additional features. But since it's also completely free, it represents a pretty nice choice for anyone looking to convert videos to the WebM format.
