gzip_types text/html text/css application/javascript application/json image/svg+xml;Frequently asked questions
Gzip or Brotli?
Brotli compresses better and is supported by all modern browsers. Gzip is a fine fallback.
Should I compress images too?
Images are already compressed formats. Optimize them separately instead.
