Common Use Cases for Webpack Compression Plugin Config Generator
React Production Build Optimization
Add pre-compression to your Create React App or custom React webpack build. The webpack compression plugin config generator produces the exact plugin configuration to pre-compress JS bundles, CSS, and HTML at build time.
Core Web Vitals Improvement
Reduce LCP and FCP by serving pre-compressed assets instead of compressing on-the-fly. Use the webpack compression plugin config generator to add Brotli pre-compression — typically 15–25% smaller than GZIP for JavaScript bundles.
Angular and Vue.js Builds
Angular CLI and Vue CLI both support custom webpack configurations via builders and vue.config.js. Use the webpack compression plugin config generator to add the CompressionPlugin to your Angular or Vue production build.
S3 + CloudFront Static Hosting
Pre-compress assets before uploading to S3 so CloudFront can serve them with the correct Content-Encoding header. The webpack compression plugin config generator creates .gz and .br files that S3 can serve directly.
Monorepo Bundle Size Reduction
Add compression to multiple webpack configs in a monorepo. The webpack compression plugin config generator supports both CommonJS and ESM module formats — copy the snippet into each package's webpack config.
CI/CD Pipeline Build Optimization
Use GZIP level 6 or Brotli quality 6 in CI/CD pipelines to balance compression ratio against build time. The webpack compression plugin config generator lets you tune the level slider to match your pipeline's time budget.
Understanding Webpack Compression Plugin Configuration
What is the Webpack Compression Plugin?
The webpack compression plugin (compression-webpack-plugin) is a webpack plugin that pre-compresses your build output at build time — creating .gz and .br files alongside the original assets. When your web server is configured to serve these pre-compressed files (via gzip_static on in Nginx), it eliminates the per-request CPU cost of on-the-fly compression. Our free webpack compression plugin config generator produces a complete, production-ready webpack.config.js snippet — all generated locally in your browser with no signup required.
How Our Webpack Compression Plugin Config Generator Works
- Configure Your Options: Select GZIP, Brotli, or both algorithms. Set compression levels, threshold, minRatio, asset pattern, and module format using the interactive controls.
- Generate Instantly:Click "Generate Config" — the webpack compression plugin config generator produces a complete webpack.config.js snippet with the correct plugin instances, entirely in your browser.
- Copy and Deploy: Install the plugin, add the snippet to your webpack config, run your build, and configure your web server to serve the pre-compressed files using the included Nginx snippet.
What the Generated Config Includes
- CompressionPlugin instances: One for GZIP (
algorithm: 'gzip') and/or one for Brotli (algorithm: 'brotliCompress') with your configured levels and options. - Threshold and minRatio:Skip compressing assets that are too small or that don't compress well enough to be worth the overhead.
- Asset pattern: A regex that matches only the file types worth compressing — JS, CSS, HTML, SVG, JSON, and WOFF2 by default.
- Nginx serve snippet: The matching
gzip_staticandbrotli_staticdirectives to serve the pre-compressed files from your web server.
Pre-Compression vs. On-the-Fly Compression
On-the-fly compression (e.g. Nginx gzip on) compresses each response at request time — adding CPU overhead and latency. Pre-compression with the webpack compression plugin compresses assets once at build time, so the server simply reads and serves the pre-compressed file with zero CPU cost per request. For static assets with high traffic, pre-compression is always preferred. The webpack compression plugin config generator makes it trivial to add pre-compression to any webpack-based project.

Frequently Asked Questions About Webpack Compression Plugin Config Generator
A webpack compression plugin config generator produces a ready-to-use webpack.config.js snippet that adds GZIP and/or Brotli pre-compression to your webpack build using the compression-webpack-plugin package. Configure compression levels, threshold, minRatio, and asset patterns — the webpack compression plugin config generator outputs the correct plugin instances instantly. Our free online webpack compression plugin config generator runs entirely in your browser with no signup required.
On-the-fly compression (e.g. Nginx gzip on) compresses each HTTP response at request time, adding CPU overhead and latency. Pre-compression with the webpack compression plugin compresses assets once at build time — the server reads and serves the pre-compressed .gz or .br file with zero CPU cost per request. For static assets with high traffic, pre-compression is always preferred.
Yes. The webpack compression plugin config generator runs entirely in your browser — all configuration generation is performed locally using JavaScript. No project details, file paths, or configuration data are sent to any server. Your settings never leave your device.
Yes. The webpack compression plugin config generator is 100% free with no signup, no subscription, and no limits. Generate configurations for as many projects as you need.
Yes — the webpack compression plugin creates .gz and .br files at build time, but your web server must be configured to serve them. For Nginx, add gzip_static on for GZIP and brotli_static on for Brotli (requires ngx_brotli module). For Apache, use mod_deflate with pre-compressed file serving. The webpack compression plugin config generator includes the Nginx snippet in the results.
For GZIP, level 9 is recommended for static pre-compression since the CPU cost is paid once at build time. For Brotli, quality 11 achieves maximum compression — typically 20–26% better than GZIP level 9. For CI/CD pipelines where build time matters, use GZIP level 6 and Brotli quality 6 to balance compression ratio against build speed.
The threshold option (in bytes) tells the plugin to skip compressing assets smaller than the specified size. The default of 10,240 bytes (10 KB) is a good starting point — compressing very small files adds overhead without meaningful savings. Increase this value if you want to skip more small files, or set it to 0 to compress everything.
The minRatio option tells the plugin to skip creating a compressed file if the compression ratio is not good enough. A minRatio of 0.8 means: only create the compressed file if it is at most 80% of the original size (i.e. at least 20% savings). Set it to 1 to always create compressed files regardless of savings, or lower it to require better compression before creating the file.
Yes. For Create React App, use react-app-rewired or CRACO to customize the webpack config. For Angular CLI, use @angular-builders/custom-webpack. For Vue CLI, add the plugin in vue.config.js under configureWebpack. The webpack compression plugin config generator produces a standard CompressionPlugin configuration that works with any webpack-based build tool.
