What is Gzip Compression?

Definition

Gzip is a file compression format and algorithm widely used for HTTP content encoding. Servers compress responses with gzip before sending, and browsers decompress them automatically. Gzip typically reduces text-based file sizes by 60-80%.

Why It Matters

Enabling gzip compression on your web server is one of the easiest performance wins. It reduces bandwidth usage and page load times with minimal CPU overhead. Almost all modern web servers and CDNs support gzip (or the newer Brotli) compression.
