About this HTTP headers parser
HTTP response headers carry metadata about the response: content type, caching, CORS, security, and more. This free online headers parser turns a raw header block—as copied from browser DevTools, curl -v, or API logs—into a clear table so you can inspect and copy individual headers or the whole block.
Common uses
- Debug CORS, cache-control, and content-type headers on API responses
- Share or document response headers from DevTools without manual formatting
- Parse folded (multi-line) headers from curl or proxy logs
Frequently asked questions
Where can I get raw HTTP headers?
In Chrome DevTools: Network tab, select a request, Headers tab, copy the Response Headers section. You can also copy from curl -v or similar tools.
Does this HTTP headers parser send data to a server?
No. Parsing runs entirely in your browser. No headers or data are uploaded.
Can I parse folded or multi-line HTTP headers?
Yes. The parser handles folded (continuation-line) headers and displays each name and value in a clear table.
