Why is Compression Important?

Compressing text-based responses (HTML, CSS, JavaScript) using algorithms like Gzip or Brotli can significantly reduce the amount of data sent over the network, leading to faster load times, reduced bandwidth costs, and better SEO rankings.

Gzip vs. Brotli

  • Gzip: The classic, most widely supported compression algorithm. It is very fast and efficient, supported by nearly every web server and browser.
  • Brotli: A newer algorithm developed by Google. It generally offers better compression ratios than Gzip (often 15-20% smaller files), meaning even faster load times. Modern browsers support Brotli over HTTPS.
