GZIP is a compression method that reduces file size during transfer, making websites load faster. This tool checks if a URL uses GZIP compression by analyzing the HTTP response headers. It shows compression status, compression ratio, and content encoding information.

Enter a URL in the input field and click Check to analyze GZIP compression. The tool will fetch the URL and examine response headers including Content-Encoding, Content-Length, and Transfer-Encoding. Results show whether GZIP is enabled and the compression ratio. Click Clear to check another URL. All processing happens locally in your browser.

GZIP compression typically reduces text file sizes by 60-80%, significantly improving page load times. Search engines like Google consider page speed as a ranking factor. Enabling GZIP on text files (HTML, CSS, JS, JSON, XML, SVG) is a standard web performance optimization.
