HTTP Headers Parser

Paste raw HTTP request or response headers to see them as a table with plain-language explanations. Runs entirely in your browser.

About this tool

Paste headers copied from a browser's network tab, a curl -i response, or a request log — one Name: Value pair per line. The first line is skipped automatically if it looks like a request/status line (e.g. GET / HTTP/1.1). Descriptions are shown for well-known headers; unrecognised headers are still parsed and shown without a description.
