What is Brotli compression and why should I use it?
How do I enable Brotli compression on my web server?
ngx_brotli module and add brotli on; brotli_types text/plain text/css application/json application/javascript; to your config. For Apache, enable mod_brotli with AddOutputFilterByType BROTLI_COMPRESS text/html text/css. If migrating from Apache, use our htaccess to nginx converter. Check our server administration cheatsheets for detailed configuration examples. After enabling, verify it works using this Brotli checker tool, then optimize your server resources with our PHP-FPM calculator. Brotli vs Gzip: Which compression should I use?
Why does Brotli require HTTPS?
How do I test if Brotli compression is working effectively?
content-encoding: br (Brotli) or content-encoding: gzip. For comprehensive testing, also use our DNS lookup tool to verify CDN configuration and port scanner to ensure HTTPS (port 443) is open. Test your site's response from multiple continents using our multi-location ping test to measure real-world performance improvements. Does Brotli work with CDNs like Cloudflare, AWS CloudFront, or Fastly?
How can I optimize my server configuration for maximum compression?
Which file types should I compress with Brotli?
My Brotli compression is not working. How do I troubleshoot?
nginx -V or apache2ctl -M for brotli modules, 3) Wrong MIME types—Verify brotli_types includes your content type, 4) CDN overriding—Check with DNS lookup if requests go through CDN, 5) Firewall blocking—Scan ports with our port scanner tool. Still stuck? Review our troubleshooting cheatsheets or contact our support team.
