What is HTTP compression?

HTTP compression is a technique that reduces the size of data transmitted between web servers and clients by encoding the content using algorithms like gzip or Brotli, resulting in faster page load times and reduced bandwidth usage.

HTTP compression works by applying compression algorithms to the server's response before sending it to the client. The most common compression methods are gzip and Brotli, with the latter generally providing better compression ratios. When a client supports compression, it includes an "Accept-Encoding" header in its request, allowing the server to respond with compressed content, which the client then decompresses before rendering.

Why is supporting HTTP compression important?

Providing support for HTTP compression is imperative in the modern age of web delivery.

• Faster page load times: Compressed content requires less time to transfer, improving user experience.
• Reduced bandwidth usage: Smaller data transfers save bandwidth for both servers and clients.
• Lower hosting costs: Less data transferred can lead to reduced costs for website owners.
• Improved mobile performance: Especially beneficial for users on slower or metered connections.
• Better search engine rankings: Faster websites often rank higher in search results.
• Increased server efficiency: Servers can handle more requests with the same resources.
• Energy savings: Less data transfer means less energy consumption, benefiting the environment.
