Frequently Asked Questions
- What is HTTP compression?
- HTTP compression reduces response sizes using algorithms like gzip, Brotli, or zstd. Browsers send an Accept-Encoding header, and servers respond with compressed content.
- Which compression should I use?
- It depends on your content and priorities. Brotli, gzip, and zstd each have different compression ratios and speed tradeoffs. Test your actual content to find the best fit.
- How do I enable compression?
- Configure your web server (Nginx, Apache) or CDN to compress responses. Most CDNs enable gzip and Brotli by default. Check the Content-Encoding header to verify.
