Additional Options

Generated next.config.mjs

/** @type {import('next').NextConfig} */
const nextConfig = {
  // Enable built-in GZIP compression for server responses
  compress: true,

  // Remove X-Powered-By header (minor security improvement)
  poweredByHeader: false,

  reactStrictMode: true,

};

export default nextConfig;

Vercel: Brotli and GZIP compression are handled automatically at the edge — no webpack plugin or custom headers needed. Set compress: true for the Node.js runtime fallback.

Verify compression is working

# Check GZIP on your Next.js app
curl -H "Accept-Encoding: gzip" -I https://yoursite.com/

# Check Brotli
curl -H "Accept-Encoding: br" -I https://yoursite.com/

# Build and check output sizes
npm run build
# Look for .gz / .br files in .next/static/

Bundle Size Optimization

Add the @next/bundle-analyzer wrapper to your next.config.js to identify large dependencies that inflate your JavaScript bundle. The next.js compression config generator includes the bundle analyzer configuration alongside compression settings for a complete optimization setup.

Understanding Next.js Compression Configuration

What is Next.js Compression Configuration?

Next.js compression configuration controls how your Next.js application compresses HTTP responses and static assets. Next.js has a built-in compressoption that enables GZIP compression for server-rendered responses using Node.js's built-in zlib module. For static assets (JavaScript, CSS, HTML), Next.js can pre-compress files at build time using the compression-webpack-plugin — generating .gz and .br files alongside the originals. Our next.js compression config generator produces a correctly formatted next.config.js or next.config.mjs tailored to your deployment target — Vercel, Node.js, static export, or Docker.

How Our Next.js Compression Config Generator Works

  1. 1Select your options: Choose your Next.js version (14 or 15), config file format (ESM or CJS), deployment target, and compression options. The next.js compression config generator updates the output in real time as you adjust each option — no button press needed.
  2. 2Review warnings and install packages: The next.js compression config generator shows deployment-specific warnings — like disabling compress: true when behind a reverse proxy — and generates the npm install command for any required packages. All generation runs in your browser.
  3. 3Copy and replace your next.config file: Click Copy to copy the generated config to your clipboard. Replace your existing next.config.js or next.config.mjs and run npm run build to apply the changes.

Key Next.js Compression Settings Explained

  • compress: true/false: Enables or disables Next.js built-in GZIP compression for server-rendered responses. Set to true for Node.js deployments without a reverse proxy. Set to false when Nginx, Caddy, or a CDN handles compression — avoids double-compression overhead.
  • compression-webpack-plugin: Pre-compresses static assets (JS, CSS, HTML, SVG, JSON) to .gz and .br files at build time. The server then serves the pre-compressed file directly — eliminating runtime compression CPU overhead. Requires server-side support (Nginx gzip_static, brotli_static, or CDN static file serving).
  • swcMinify: true: Uses the SWC compiler for JavaScript minification instead of Terser — 17× faster with equivalent output size. Default in Next.js 13+ and the only option in Next.js 15.
  • @next/bundle-analyzer: Wraps the Next.js config to add bundle visualization. Run ANALYZE=true npm run build to open an interactive treemap of your JavaScript bundle — identifies large dependencies that inflate transfer size.

Compression Strategy by Deployment Target

Vercel: Brotli and GZIP are handled automatically at the edge — set compress: true for the Node.js runtime fallback and skip the webpack plugin. Node.js server: Enable compress: true for dynamic responses and use the webpack plugin for static assets. Docker behind Nginx: Disable compress: false and configure Nginx GZIP/Brotli — avoids double-compression. Static export: Use the webpack plugin to pre-compress all static files and configure your CDN or Nginx to serve the pre-compressed variants. Use the next.js compression config generator to get the correct configuration for your specific deployment.

Frequently Asked Questions About Next.js Compression Config Generator

A next.js compression config generator produces a ready-to-paste next.config.js or next.config.mjs with optimized compression settings for your deployment target. Our free next.js compression config generator online supports Vercel, Node.js, static export, and Docker deployments — with real-time warnings for common misconfigurations. All generation runs in your browser.

Set compress: true if your Next.js server handles responses directly (Node.js deployment without a reverse proxy, or Vercel). Set compress: false if Nginx, Caddy, or a CDN handles compression in front of Next.js — this avoids double-compression overhead where both Next.js and the proxy compress the same response.

Yes — Vercel automatically applies Brotli and GZIP compression at the edge for all responses. You do not need the compression-webpack-plugin or custom headers on Vercel. Set compress: true for the Node.js runtime fallback and let Vercel handle the rest.

Yes. All config generation runs entirely in your browser using JavaScript. No configuration data is sent to any server, stored remotely, or transmitted over the network. The next.js compression config generator is completely safe for configuring production Next.js applications.

Yes — 100% free, forever. No signup, no account, no premium tier, and no ads. Generate unlimited Next.js compression configurations completely free.

next.config.mjs uses ES Module syntax (import/export) and is the default for new Next.js 14+ projects. next.config.js uses CommonJS syntax (require/module.exports) and is compatible with older projects. Both work identically — choose based on your project's module system. If your package.json has "type": "module", use .mjs.

Install compression-webpack-plugin and add it to your webpack config in next.config.js with algorithm: "brotliCompress". This generates .br files alongside your .js and .css files in .next/static/. Configure your server to serve the pre-compressed files: Nginx needs brotli_static on, Caddy uses file_server with precompressed br gzip.

swcMinify: true uses the SWC Rust-based compiler for JavaScript minification instead of Terser. SWC is approximately 17× faster than Terser and produces equivalent or smaller output. It is the default in Next.js 13+ and the only option in Next.js 15 (swcMinify was removed as a config option since it is always enabled).

Test with curl: "curl -H "Accept-Encoding: gzip" -I https://yoursite.com/" and look for Content-Encoding: gzip in the response headers. For Brotli: "curl -H "Accept-Encoding: br" -I https://yoursite.com/". In browser DevTools, check the Network tab → select a JS or CSS file → Response Headers → Content-Encoding.
