Compressing JSON: gzip, Brotli, and Structural Compression Compared JSON is notoriously verbose. A typical API response spends significant bytes on repeated key names, whitespace, and string delimiters. Compression exploits this repetition aggressively — JSON compresses better than almost any other text format because of its predictable structure. Understanding which compression strategy applies where, and when compression stops helping, determines whether you're shipping 200 KB or 40 KB over the wire. HTTP Content-Encoding: gzip and Brotli The most universally applicable compression is transport-level: gzip or Brotli applied to the HTTP response body. The client signals support via the request header; the server compresses and sets in the response. Typical reduction ratios for JSON…
