Tips
Serving both GZIP and Brotli lets your server choose the best format per client. Brotli is served to modern browsers; GZIP is the fallback for older clients.
vite-plugin-compression only runs during production builds (vite build). Development mode (vite dev) is not affected.

})vite-plugin-compression pre-compresses assets at build time — your server serves the .gz or .br files directly without runtime CPU overhead. Requires server-side support for gzip_static (nginx) or equivalent CDN configuration.

Common Use Cases for Vite Compression Plugin Config Generator
React + Vite Production Optimization
Add GZIP and Brotli pre-compression to your React + Vite build — reduces JS bundle transfer size by 60–80% and eliminates runtime compression CPU overhead on your server.
Vue 3 + Vite Bundle Compression
Configure vite-plugin-compression for Vue 3 projects — pre-compress vendor chunks, component bundles, and CSS files at build time for maximum CDN delivery performance.
Core Web Vitals Improvement
Pre-compressed assets load faster than runtime-compressed ones — eliminate the server-side compression delay and improve LCP scores by serving .gz and .br files directly.
nginx Static File Serving
Generate the matching nginx.conf snippet for serving pre-compressed Vite build assets — configure gzip_static and brotli_static to serve .gz and .br files automatically.
CDN & Object Storage Deployment
Upload pre-compressed .gz and .br files to S3, CloudFront, or Cloudflare R2 — serve them with the correct Content-Encoding header to eliminate CDN compression overhead.
CI/CD Pipeline Integration
Add vite-plugin-compression to your CI/CD build step — pre-compress all assets at build time so your deployment pipeline produces optimally compressed artifacts.
Understanding Vite Build Compression
What is Vite Compression Plugin?
vite-plugin-compression is a Vite plugin that pre-compresses build output files (JavaScript bundles, CSS, HTML) to GZIP and/or Brotli format at build time. Instead of compressing files on every HTTP request (runtime compression), the server serves the pre-compressed .gz or .br files directly — eliminating runtime CPU overhead and producing faster response times. Our free Vite compression plugin config generator produces the correct vite.config.ts for your framework and settings.
How Our Vite Compression Config Generator Works
- Select Your Settings: Choose your framework (React, Vue, Svelte, etc.), compression algorithm (GZIP, Brotli, or both), threshold, compression levels, and package manager.
- Instant Config Generation: The generator instantly produces three outputs — install command, vite.config.ts with framework-specific imports, and nginx.conf snippet — all updating in real time.
- Copy and Apply: Switch between the three tabs, copy the relevant configuration, and add it to your Vite project and server configuration.
Pre-compression vs Runtime Compression
- Runtime compression (nginx gzip on): Compresses files on every request — adds CPU overhead, increases response time, and requires server resources.
- Pre-compression (vite-plugin-compression): Compresses files once at build time — zero runtime CPU overhead, instant response, and works with any static file server or CDN.
- Best practice: Use both — pre-compress with vite-plugin-compression and enable gzip_static in nginx as a fallback for files without pre-compressed versions.
- CDN compatibility: Upload .gz and .br files to S3, CloudFront, or Cloudflare R2 and serve them with the correct Content-Encoding header.
GZIP vs Brotli for Vite Builds
Brotli achieves 15–25% better compression than GZIP for JavaScript and CSS bundles. It is supported by all modern browsers (Chrome, Firefox, Edge, Safari 17.4+). GZIP is the universal fallback — supported by all browsers and servers. For maximum compatibility, generate both formats and let your server choose the best one per client. Brotli compression at quality 6 is a good balance between compression ratio and build time.

Frequently Asked Questions About Vite Compression Plugin Config Generator
vite-plugin-compression is a Vite plugin that pre-compresses build output files (JS, CSS, HTML) to GZIP and/or Brotli format at build time. This eliminates runtime compression CPU overhead on your server and produces smaller files for CDN delivery. Our free online config generator produces the correct vite.config.ts — no signup required.
Runtime compression (nginx gzip on) compresses files on every request, adding CPU overhead. Pre-compression (vite-plugin-compression + nginx gzip_static) compresses files once at build time and serves the pre-compressed .gz or .br files directly — zero runtime CPU overhead and faster response times.
Yes. The Vite compression config generator is 100% free with no signup, no subscription, and no limits. You can generate as many configurations as you need.
Use both GZIP and Brotli for maximum compatibility. Brotli achieves 15–25% better compression than GZIP and is supported by all modern browsers. GZIP is the fallback for older browsers and tools. Your server (nginx with gzip_static + brotli_static) will serve the best format each client supports.
The threshold controls the minimum file size for compression. Files smaller than the threshold are not compressed — compressing very small files can actually increase their size due to compression headers. 10 KB is a good default. For aggressive compression, use 1 KB.
Only delete originals if your server is configured to serve .gz/.br files exclusively and you are certain all clients support the compressed format. For most setups, keep the originals — your server will serve the compressed version when the client supports it and fall back to the original otherwise.
vite-plugin-compression works with Vite's client-side build output. For SSR builds, the plugin compresses the client bundle but not the server bundle. Configure your SSR server to handle compression separately using middleware like the compression npm package.
Enable gzip_static on in your nginx server block to serve .gz files automatically. For Brotli, install the ngx_brotli module and enable brotli_static on. The nginx.conf tab in this generator produces the exact configuration snippet you need.
