When video, photo or music is saved in a
digital format the result can be a huge file that is hard to stream and uses up a lot of memory on the computer or hard drive to which it is saved. In order to save space files are made smaller by removing some of the data. This is referred to as "compression". For an in-depth look at media file compression and how it works, read
