This online web tool allows you to quickly check whether GZIP compression is enabled on your website. GZIP compression is a widely used method that reduces the size of files sent from your web server to visitors’ browsers, which can significantly improve loading times and overall website performance.

When GZIP is enabled, files such as HTML, CSS, and JavaScript are compressed on the server before being sent over the internet. Once the compressed files reach the visitor’s browser, they are automatically decompressed, allowing the page to display normally. This entire process happens almost instantly and is completely transparent to the end user.

Enabling GZIP compression can reduce the size of transmitted files by 50% to 80%, which not only speeds up page load times but also reduces bandwidth usage and server load. Faster websites improve user experience, enhance SEO rankings, and can even lower hosting costs for high-traffic sites.

Simply enter your website’s URL into this tool to find out if GZIP compression is active and ensure your site is delivering content as efficiently as possible.
