HandBrake is a tool for converting video from nearly any format to a selection of modern, widely supported codecs. It is free and open source and available for Windows, Mac, and Linux. Handbrake offers a variety of device presets to convert media to suit your device needs. For instance, if you had a very large video file you wanted to scale down for viewing on a phone without taking up too much space, you could use an easy filter to convert the media for that specific situation. Handbrake can also convert DVDs to video files, encode chapter markers, subtitles, and menus.
