How to use Website Gzip Checker
- Enter the page or asset URL you want to test.
- Run the checker and review content-encoding, transfer hints, and relevant response headers.
- Adjust server, CDN, or hosting compression settings if eligible text assets are uncompressed.
Why use Website Gzip Checker
Compression can reduce the transfer size of HTML, CSS, JavaScript, JSON, SVG, and other text-based assets. If it is missing, pages may load slower than necessary even when the source files are already minified.
This checker helps confirm what the server actually sends. It is useful after CDN setup, hosting migrations, cache rule changes, and performance audits where the browser waterfall suggests large text transfers.
Best for Gzip Checker
- Verifying gzip or Brotli after deployment.
- Checking HTML, CSS, JS, JSON, and SVG delivery.
- Finding compression gaps during performance work.
Practical notes
- Images and already-compressed files may not benefit much.
- CDN cache can delay compression rule changes.
- Check important asset URLs as well as the homepage.
