Content-Encoding

Specifies the compression algorithm applied to the response body, such as gzip or brotli.

Syntax

Content-Encoding: gzip | br | deflate | identity

Example

Content-Encoding: gzip

Description

Content-Encoding indicates the compression algorithm applied to the response. The browser decompresses content before processing.

Common values: gzip (widely supported), br (Brotli, better compression), deflate (legacy). Selected based on Accept-Encoding.

Compression reduces transfer sizes by 60-80% for text resources. Enable both gzip and Brotli for optimal results.
