How It Works:

  1. User enters a URL to test

  2. The tool fetches the URL with Accept-Encoding: gzip, deflate, br header

  3. Analyzes the content-encoding response header

  4. Determines if Gzip, Brotli, or other compression is enabled

  5. Displays detailed results with recommendations

About Compression

Why Enable Compression?

Compression reduces file sizes by up to 70-90%, speeding up page load times and improving user experience.

Gzip vs Brotli

Gzip is widely supported and provides good compression. Brotli (by Google) offers 20-26% better compression than Gzip.

How to Enable

Enable compression via your web server configuration (Apache, Nginx) or CDN settings (Cloudflare, AWS CloudFront).

Note: Due to CORS restrictions, some websites may not return full headers. For complete testing, use browser developer tools.
