Common Use Cases for Nginx Brotli Config Generator
New Nginx Server Setup
Use the Nginx Brotli config generator when setting up a new web server to get a complete, production-ready Brotli configuration from the start — including the correct module loading directive and MIME type list.
CDN Origin Server Optimization
Configure Brotli on your Nginx origin server so your CDN can cache and serve Brotli-compressed responses. The Nginx Brotli config generator includes the brotli_vary directive to ensure correct CDN cache keying.
Static Site Hosting
Enable brotli_static mode to serve pre-compressed .br files alongside your static assets. The Nginx Brotli config generator provides the shell script to pre-compress your build output after each deployment.
React / Next.js Production Deployment
Optimize Nginx for serving React or Next.js production builds. The Nginx Brotli config generator includes the correct MIME types for JavaScript bundles, JSON manifests, and WOFF2 fonts used by modern web apps.
Migrating from GZIP to Brotli
Add Brotli compression to an existing Nginx server that already uses GZIP. Enable the GZIP fallback option in the Nginx Brotli config generator to maintain compatibility with older clients while serving Brotli to modern browsers.
Core Web Vitals Improvement
Reduce LCP and FCP times by enabling Brotli compression on your Nginx server. The Nginx Brotli config generator targets the exact MIME types that contribute most to page weight — HTML, CSS, JavaScript, and JSON.
Understanding Nginx Brotli Configuration
What is Nginx Brotli Configuration?
Nginx Brotli configuration enables the ngx_brotlimodule to compress HTTP responses using Google's Brotli algorithm before sending them to clients. Brotli achieves 15–25% better compression than GZIP at comparable CPU cost, making it the preferred compression format for modern web delivery. Our free Nginx Brotli config generator produces a complete, production-ready nginx.conf snippet with the correct directives, MIME types, and optional GZIP fallback — all generated locally in your browser with no signup required.
How Our Nginx Brotli Config Generator Works
- Configure Your Settings: Select compression level (1–11), brotli_static mode, installation method, MIME types, and optional GZIP fallback using the interactive controls.
- Generate Instantly:Click "Generate Config" — the Nginx Brotli config generator produces a complete nginx.conf snippet with all selected options applied, entirely in your browser.
- Copy and Deploy: Copy the generated config, follow the installation steps, and verify with the provided curl command. For static mode, use the included pre-compression shell script.
What the Generated Config Includes
- Module Loading: The correct
load_moduledirectives for dynamic installation, or a note for statically compiled or OpenResty setups. - Core Directives:
brotli on,brotli_comp_level,brotli_static,brotli_min_length, andbrotli_vary. - MIME Type List: All standard compressible MIME types plus optional web fonts, SVG images, JSON-LD, and XML variants based on your selections.
- GZIP Fallback:An optional GZIP block for clients that don't support Brotli — ensures all browsers receive compressed responses.
Choosing the Right Compression Level
The Nginx Brotli config generator supports all 11 Brotli compression levels. Level 6 is the recommended default for most deployments — it achieves near-maximum compression with reasonable CPU cost. For dynamic responses (API endpoints, server-rendered HTML), use level 4–5 to minimize added latency. For static pre-compression (with brotli_static on), use level 11 — the CPU cost is paid once at build time, not per request. Level 11 typically achieves 20–26% better compression than GZIP level 9.

Frequently Asked Questions About Nginx Brotli Config Generator
An Nginx Brotli config generator produces a ready-to-use nginx.conf snippet that enables Brotli compression on your Nginx web server. Configure compression level, static mode, MIME types, and GZIP fallback — the Nginx Brotli config generator outputs the correct directives instantly. Our free online Nginx Brotli config generator runs entirely in your browser with no signup required.
With brotli_static on, Nginx serves a pre-compressed .br file if it exists alongside the original file, and falls back to dynamic compression if not. With brotli_static always, Nginx always serves the .br file and returns a 404 if it does not exist — use this only when you are certain all files have been pre-compressed. The "on" mode is safer for most deployments.
Yes. The Nginx Brotli config generator runs entirely in your browser — all configuration generation is performed locally using JavaScript. No server details, domain names, or configuration data are sent to any server. Your settings never leave your device.

On Ubuntu/Debian, run: sudo apt install libnginx-mod-http-brotli-filter libnginx-mod-http-brotli-static. This installs the dynamic modules and automatically adds the load_module directives. Alternatively, you can compile Nginx from source with the ngx_brotli module from github.com/google/ngx_brotli, or use OpenResty which includes Brotli support by default.
Level 6 is the recommended default for dynamic compression — it achieves near-maximum compression with reasonable CPU cost. For static pre-compression (brotli_static), use level 11 since the CPU cost is paid once at build time. For high-traffic API endpoints where latency matters, use level 4–5. Levels 1–3 are only useful for extremely latency-sensitive dynamic content.
Yes — always keep GZIP as a fallback. While Brotli is supported by ~96% of browsers, some clients (older browsers, HTTP/1.0 proxies, some API clients) only support GZIP. Nginx automatically negotiates the best encoding based on the client's Accept-Encoding header, so both can coexist without any manual routing logic.
The brotli_vary on directive adds the Vary: Accept-Encoding response header. Without this, CDNs and reverse proxies may cache a Brotli-compressed response and serve it to clients that only support GZIP — causing decompression errors. Always enable brotli_vary when using Brotli compression behind a CDN or caching proxy.
Run: curl -H "Accept-Encoding: br" -I https://yourdomain.com/ and check for Content-Encoding: br in the response headers. You can also use browser DevTools → Network tab → select a request → Headers → look for Content-Encoding: br. The Vary: Accept-Encoding header should also be present.
