Brotli Checker – Free Online Tool
Our free Brotli Checker tests whether a website compresses its files with Brotli, the modern compression method that makes pages smaller and faster than Gzip.
What is Brotli Checker?
Brotli is a compression algorithm developed by Google. Servers use it to shrink HTML, CSS and JavaScript before sending them to the browser, often making files 15–25% smaller than with Gzip.
Smaller files mean faster loading, especially on mobile connections.

Frequently asked questions
Is Brotli better than Gzip?
Brotli usually compresses text files more efficiently, while Gzip remains a good fallback.
How do I enable Brotli?
Many hosts and CDNs such as Cloudflare offer a simple toggle; on your own server it requires a Brotli module.
Does Brotli work with images?
Images are already compressed, so Brotli is mainly for text files.
