This tool checks if your website (and the server hosting it) supports Gzip or Brotli compression. It does this by connecting to your domain and inspecting the server's response headers. Additionally, it provides extra details such as the size of your webpage before compression and the potential space savings with compression enabled.
What does Gzip compression do?
Gzip is a widely used compression method that shrinks the size of website files—mainly HTML, CSS, and JavaScript—by up to 70%-80%. The compressed version is delivered to the visitor's browser, which then decompresses it automatically to display the original content, reducing load time and saving bandwidth.
How does enabling Gzip / Brotli make my website faster?
Smaller compressed files mean faster downloads, which improves overall page load speed. You can use the waterfall chart in our page speed test to see how much compression each file on your website is receiving.
How do I enable Gzip?
Visit our step-by-step guide for detailed instructions on enabling Gzip and learning more about how it works.
What is Brotli?
Brotli is a modern, open-source compression algorithm. In most scenarios, it delivers better compression rates than Gzip and also decompresses files more quickly. This makes it an excellent alternative for improving web performance.
Should I use Brotli instead of Gzip?
While Brotli is supported by all major browsers, there are still a few that do not support it. You can configure your server to serve Brotli to supported browsers and fall back to Gzip for others. We'll be sharing more details on how to set that up soon!
