Alternatively called compacting, compressing is taking one or more files and combining them or making them smaller by utilizing an algorithm in a compression utility. Commonly, file compression removes redundancies or specific data that is not essential. For example, a tiny JPEG (Joint Photographic Experts Group) for use on a web page.
What are the benefits of compressed files?
Compressed files (e.g., .zip files) make it so users can share and download a single file, rather than getting multiple files from many different locations or links. Compression has greatly improved the speeds at which images and music can be downloaded and reduces load times of Internet sites.
