Why Use Our Apache mod_brotli Config Generator?

Instant Apache mod_brotli Configuration

Generate a production-ready Apache mod_brotli configuration instantly — no Apache documentation lookup, no syntax errors, no trial and error. The apache mod_brotli config generator produces a correctly formatted config block with recommended quality settings and MIME types in seconds.

Secure Apache mod_brotli Config Generator Online

Your configuration choices never leave your device. The apache mod_brotli config generator runs entirely in your browser — no server requests, no data retention, 100% private. Safe for configuring production Apache servers with sensitive MIME type and path configurations.

Apache mod_brotli Config Generator — No Installation

Generate Apache mod_brotli configurations directly in any modern browser with no software downloads, no Apache installation, and no account required. The apache mod_brotli config generator works on Windows, macOS, Linux, and mobile.

Fully Configurable with Real-Time Warnings

The apache mod_brotli config generator lets you configure Brotli quality (1–11), MIME types, config placement, exclusion rules, and logging — with real-time warnings for common misconfigurations like missing Vary headers, compressing WOFF2 fonts, and using high quality levels for dynamic content.

Common Use Cases for Apache mod_brotli Config Generator

Enabling Brotli on a New Apache Server

When setting up a new Apache web server, use the apache mod_brotli config generator to produce a complete, correctly formatted mod_brotli configuration block — including MIME types, quality settings, and a GZIP fallback — ready to paste into httpd.conf or apache2.conf.

Upgrading from mod_deflate to mod_brotli

If your Apache server currently uses mod_deflate (GZIP) and you want to add Brotli support, the apache mod_brotli config generator produces a configuration that includes both mod_brotli and a mod_deflate fallback — ensuring all clients receive compressed responses regardless of Brotli support.

WordPress and PHP Application Optimization

Enable Brotli compression for WordPress, Laravel, or other PHP applications running on Apache. The apache mod_brotli config generator produces a VirtualHost or .htaccess configuration that compresses HTML, CSS, JavaScript, and JSON responses — reducing page weight by 20–30% compared to GZIP.

Shared Hosting .htaccess Configuration

On shared hosting where you cannot modify httpd.conf, use the apache mod_brotli config generator to produce a .htaccess configuration. Select the ".htaccess" placement option to get a configuration with the correct AllowOverride notes and module availability checks.

Per-VirtualHost Brotli Configuration

Configure Brotli compression differently for different virtual hosts — for example, using quality 6 for a dynamic application and quality 11 for a static site. The apache mod_brotli config generator produces a VirtualHost-scoped configuration block that overrides global settings for a specific domain.

Avoiding Common mod_brotli Misconfigurations

The apache mod_brotli config generator includes real-time warnings for the most common mod_brotli mistakes — missing Vary headers that break CDN caching, compressing WOFF2 fonts that are already Brotli-compressed, and using quality 11 for dynamic responses that adds latency without meaningful size benefit.

Understanding Apache mod_brotli Configuration

What is Apache mod_brotli?

mod_brotli is an Apache HTTP Server module introduced in Apache 2.4.26 that compresses HTTP responses using the Brotli algorithm (RFC 7932) before sending them to clients. Brotli achieves 15–25% better compression than GZIP for text-based content — HTML, CSS, JavaScript, JSON, and XML — by using a combination of LZ77 back-references, Huffman coding, and a built-in static dictionary of common web strings. The apache mod_brotli config generator produces a complete configuration block with AddOutputFilterByType BROTLI_COMPRESS directives, quality settings, and a mod_deflate GZIP fallback for clients that do not support Brotli.

How Our Apache mod_brotli Config Generator Works

  1. 1Configure your options: Select the Brotli quality level (1–11), minimum response length, config placement (global httpd.conf, VirtualHost, Directory, or .htaccess), MIME types to compress, and additional options like Vary headers and exclusion rules. The apache mod_brotli config generator updates the output in real time as you change settings.
  2. 2Review warnings: The apache mod_brotli config generator checks your configuration for common mistakes — missing Vary headers, compressing already-compressed formats, and using high quality levels for dynamic content — and displays warnings in real time. All generation runs in your browser with no data sent to any server.
  3. 3Copy and deploy:Click "Copy" to copy the generated configuration to your clipboard. Paste it into your Apache configuration file at the indicated location, then reload Apache with sudo systemctl reload apache2 or sudo apachectl graceful.

Key mod_brotli Directives

  • BrotliCompressionQuality: Sets the Brotli compression quality from 1 (fastest, least compression) to 11 (slowest, maximum compression). Quality 6 is recommended for dynamic content; quality 11 for pre-compressed static assets.
  • AddOutputFilterByType BROTLI_COMPRESS: Applies Brotli compression to responses with the specified MIME types. Only text-based formats benefit — binary formats like images and video are already compressed and should be excluded.
  • Header append Vary Accept-Encoding: Adds the Vary: Accept-Encoding response header, which tells CDNs and caching proxies to store separate cached versions for Brotli-compressed and uncompressed responses.
  • SetEnvIfNoCase Request_URI: Sets environment variables based on the request URI — used to exclude pre-compressed file types (images, video, archives) from Brotli compression using the no-brotli environment variable.

mod_brotli vs mod_deflate — When to Use Each

mod_brotli (Brotli) achieves 15–25% better compression than mod_deflate (GZIP) for text-based content, but requires Apache 2.4.26+ and is only sent to clients that include br in their Accept-Encoding header — all modern browsers over HTTPS. Always include a mod_deflate GZIP fallback for older clients and HTTP/1.0 proxies. The apache mod_brotli config generator includes both blocks automatically. For static assets, consider pre-compressing files at build time with quality 11 and serving them with mod_brotli static serving — this eliminates runtime CPU overhead entirely.

Frequently Asked Questions About Apache mod_brotli Config Generator

An Apache mod_brotli config generator creates ready-to-paste Apache configuration for enabling Brotli compression on your web server. Our free apache mod_brotli config generator online produces configuration for httpd.conf, VirtualHost blocks, Directory blocks, or .htaccess files — with quality settings, MIME type filters, and a GZIP fallback. No signup required.

mod_brotli is an Apache HTTP Server module (available since Apache 2.4.26) that compresses HTTP responses using the Brotli algorithm before sending them to clients. Brotli achieves 15–25% better compression than GZIP for text-based content like HTML, CSS, JavaScript, and JSON, reducing bandwidth usage and improving page load times.

Quality 6 is recommended for dynamic content — it provides a good balance between compression ratio and CPU overhead. Quality 11 (maximum) is best for pre-compressed static assets where CPU time is not a concern. Avoid quality 10–11 for dynamic responses as the encoding time significantly increases server response latency.

Yes, completely. The apache mod_brotli config generator runs entirely in your browser. No configuration data, server details, or MIME type choices are sent to any server. All config generation happens locally with complete privacy.

On Debian/Ubuntu: run "sudo a2enmod brotli && sudo systemctl reload apache2". On RHEL/CentOS: add "LoadModule brotli_module modules/mod_brotli.so" to httpd.conf and restart Apache. Verify it is loaded with "apache2ctl -M | grep brotli". Apache 2.4.26 or later is required.

Yes — always include a mod_deflate (GZIP) fallback. Brotli is supported by all modern browsers over HTTPS, but some older clients, HTTP/1.0 proxies, and non-browser HTTP clients may not send "Accept-Encoding: br". The apache mod_brotli config generator includes a mod_deflate fallback block automatically.

The Vary: Accept-Encoding header tells CDNs and caching proxies to store separate cached versions for Brotli-compressed and uncompressed responses. Without it, a CDN might serve a Brotli-compressed response to a client that does not support Brotli, causing garbled output. The apache mod_brotli config generator enables this header by default.
