Warning

Brotli compression will be enabled by default for all zones on 2024-08-15. The Brotli setting will be gradually removed until then.

Enterprise customers can override Cloudflare’s default compression behavior using Compression Rules.

By default, Brotli compression is enabled for domains on Free and Pro plans and disabled for domains on Business and Enterprise plans.

To enable Brotli compression:

1. Log in to the Cloudflare dashboard ↗, and select your account and website.
2. Go to Speed > Optimization > Content Optimization.
3. For Brotli, toggle the switch to On.

Notes about end-to-end compression

Even when using the same compression algorithm end to end (between your origin server and Cloudflare, and between the Cloudflare global network and your website visitor), Cloudflare will need to decompress the response and compress it again if you enable any of the following settings for the request:

• Automatic HTTPS Rewrites
• Cloudflare Fonts
• Email Address Obfuscation
• Mirage
• Polish
• Rocket Loader
• JavaScript detections
• RUM

To disable these settings for specific URI paths, create a configuration rule.

Note

Additionally, the Replace insecure JS libraries setting also requires Cloudflare to decompress the response and compress it again. At this time, you cannot turn it off using Configuration Rules.
