Gzip Compression
Gzip compression is a data compression method applied at the server level to reduce the size of HTML, CSS, JavaScript, and XML files before they are sent to the browser. Named after the GNU zip program, gzip can reduce file sizes by 60–80%, significantly decreasing page load times and bandwidth consumption.
Gzip implementation is configured via web server settings (Apache .htaccess, nginx.conf) and verified using GTmetrix, Google PageSpeed Insights, or the "Check GZIP Compression" tool at GIDZipTest.com. Google PageSpeed Insights flags missing Gzip/Brotli compression under its "Enable text compression" audit.
