For example, the most common lossless compression format ZIP is often used for program files in Windows, as it preserves all the original information. Decompressing the file unzipping produces an executable program that would otherwise be useless with lossy. Lossless formats for video are rare, as the source files would take up massive amounts of space.

Compressing a file into a ZIP may reduce its size, but it is impossible to continue compressing the file further and reduce the size to nothing. How does data compression work from a technical standpoint? Well, the actual algorithms that decide what data gets thrown out in lossy methods and how to best store redundant data in lossless compression are extremely complicated.

This overview of data compression is meant to serve as a high-level overview of the basics and provide context for how to apply these practices in real-world situations.
