Configure your Cloudflare plan, Brotli, minification, and caching settings — generates step-by-step dashboard instructions, Cache Rules configuration, a Worker script, and recommended Cache-Control headers for your origin server.
Your Cloudflare Configuration
Brotli is available on all plans
Tips
Brotli is enabled — Cloudflare will serve Brotli to browsers that support it (Chrome, Firefox, Edge, Safari 17.4+) and fall back to GZIP automatically.
Cloudflare minification is applied at the edge — it does not modify your origin files. For best results, also minify at build time.
Aggressive caching caches all static assets including query strings. Ensure your assets use content-hashed filenames for cache busting.
1-year browser TTL requires content-hashed filenames (e.g. app.abc123.js) — otherwise users will not receive updates until the cache expires.

Browser Cache TTL: 1 year (Caching → Configuration → Browser Cache TTL)
Settings are generated based on your selections above. Cloudflare's dashboard UI may differ slightly between plans. Always test compression settings in a staging environment before applying to production.

Common Use Cases for Cloudflare Compression Settings Guide
New Cloudflare Setup
Configure Brotli, minification, and caching correctly when setting up Cloudflare for the first time — the guide generates step-by-step dashboard instructions for your specific plan.
Core Web Vitals Optimization
Enable Brotli compression and aggressive caching to improve LCP and FID scores — the guide shows which Cloudflare settings have the most impact on Core Web Vitals.
Static Site Deployment
Configure optimal caching for static sites deployed to Cloudflare Pages — set 1-year browser TTL for hashed assets and generate the correct Cache-Control headers for your origin.
API & Backend Compression
Generate a Cloudflare Worker script that adds Vary: Accept-Encoding headers to API responses — ensures CDN caches compressed and uncompressed versions separately.
Next.js & SPA Deployment
Configure Cloudflare for Next.js and single-page applications — disable Rocket Loader for SPAs, set aggressive caching for static chunks, and generate Cache Rules for the app.
Compression Audit & Review
Review your current Cloudflare compression settings against best practices — the guide highlights plan-specific limitations and warns about common misconfiguration patterns.
Understanding Cloudflare Compression Settings
What is the Cloudflare Compression Settings Guide?
The Cloudflare Compression Settings Guide generates a complete compression configuration for your Cloudflare-protected website — including step-by-step dashboard instructions, Cache Rules, a Worker script for custom headers, and recommended Cache-Control headers for your origin server. Select your plan and preferences and the guide instantly generates all four output formats ready to copy and paste.
How Our Cloudflare Compression Guide Works
- Select Your Settings: Choose your Cloudflare plan, Brotli setting, Auto Minify options, caching level, TTL values, Rocket Loader, and Polish.
- Instant Config Generation: The guide instantly generates four output formats — dashboard steps, Cache Rules, Worker script, and Cache-Control headers — all updating in real time as you change settings.
- Copy and Apply: Switch between the four tabs, copy the relevant configuration, and apply it to your Cloudflare dashboard or origin server.

Brotli vs GZIP on Cloudflare
Cloudflare serves Brotli to browsers that support it (Chrome, Firefox, Edge, Safari 17.4+) and automatically falls back to GZIPfor older browsers. Brotli achieves 15–25% better compression than GZIP for text content. Enabling Brotli on Cloudflare is free on all plans and requires a single toggle in the dashboard — it is one of the highest-impact, lowest-effort performance improvements available.

Frequently Asked Questions About Cloudflare Compression Settings Guide

Yes. Cloudflare supports Brotli compression on all plans (Free, Pro, Business, Enterprise). When enabled, Cloudflare serves Brotli to browsers that support it (Chrome, Firefox, Edge, Safari 17.4+) and automatically falls back to GZIP for older browsers. Enable it in Speed → Optimization → Content Optimization → Brotli.
Yes. The guide is 100% free with no signup, no subscription, and no limits. You can generate as many configurations as you need.
Brotli is HTTP-level compression applied to the response body — it reduces transfer size without changing the content. Auto Minify removes whitespace and comments from HTML, CSS, and JavaScript at the edge — it changes the content but does not compress it. Both can be used together for maximum savings.
Polish is Cloudflare's image optimization feature that compresses and converts images at the edge. Lossless Polish removes metadata without quality loss. Lossy Polish applies additional compression with minor quality reduction. Both require a Pro plan or higher — Polish is not available on the Free plan.
Browser Cache TTL controls how long the visitor's browser caches the response. Edge Cache TTL controls how long Cloudflare's CDN caches the response at the edge. For static assets with content-hashed filenames, set both to 1 year. For HTML pages, set Browser Cache TTL to 0 (respect origin) and Edge Cache TTL to 1 hour.
Rocket Loader asynchronously loads JavaScript to improve page load times. It works well for traditional websites but can cause issues with single-page applications (React, Vue, Angular) and sites that rely on synchronous script execution order. Disable it for SPAs and test carefully before enabling on production.
The Vary: Accept-Encoding header tells CDNs (including Cloudflare) to cache separate versions of a response for compressed and uncompressed clients. Without it, Cloudflare might serve a Brotli-compressed response to a client that does not support Brotli. The Worker script in this guide automatically adds this header to compressible responses.
