How does the GZip algorithm work? [closed]

What compression does gzip use?

The gzip format is used in HTTP compression, a technique used to speed up the sending of HTML and other content on the World Wide Web. It is one of the three standard formats for HTTP compression as specified in RFC 2616.

Is gzip open source?

Gzip (GNU zip) is a free and open source algorithm for file compression. The software is overseen by the GNU project.

Is gzip lossy?

Examples of lossless compression include GZIP, Brotli, WebP, and PNG, Lossy compression, on the other hand, uses inexact approximations by discarding some data from the original file, making it an irreversible compression method.

If you're still looking for a more detailed overview, I've written up a description of the gzip deflate process, along with source code, at: http://www.infinitepartitions.com/art001.html
