Why Analyze Compression?

Modern web servers and CDNs automatically compress text assets using Gzip or Brotli before sending them to the browser. Analyzing these ratios helps you understand the true "over-the-wire" cost of your payloads.

• Gzip: The standard for HTTP compression, using the DEFLATE algorithm.
• Deflate: A raw compression format often used in zip files and PDF streams.
• Optimizing Payloads: High compression ratios (e.g., >80%) usually indicate repetitive data in your JSON or HTML.
