What is GZIP Compression?

GZIP compression is a method that compresses files before they are sent from a web server to a browser. It works by reducing the size of HTML, CSS, JavaScript, and other text-based files, ensuring faster delivery. When a web browser requests a page, the server compresses the content using GZIP, and the browser then decompresses it before displaying it.

For example, an uncompressed 100KB HTML file can be reduced to around 20KB with GZIP compression, leading to much faster load times.
