Brotli Checker

Our Brotli Checker determines whether a website uses Brotli compression, an advanced algorithm that typically reduces file sizes 20-25% more efficiently than gzip while using fewer server resources. Developed by Google, Brotli has become increasingly important for web performance optimization, as smaller file sizes lead to faster page loads, reduced bandwidth costs, and improved user experience—especially on mobile connections. This diagnostic tool helps web developers, performance engineers, and site administrators verify Brotli implementation and troubleshoot compression configurations. The checker analyzes HTTP response headers to determine if Brotli encoding is active and properly working for text-based assets like HTML, CSS, and JavaScript. Performance-conscious website owners use it to confirm their servers are delivering optimally compressed content, while developers use it to verify configuration changes. Whether you're optimizing your own website, researching competitor implementations, or evaluating hosting providers based on modern compression support, this tool provides immediate verification of Brotli capability without requiring server access or specialized software.
