Security header extraction workflows
Use this extractor when copied response headers need a local inventory before a release review, CDN migration, documentation cleanup, or security handoff.
Break down policies
Pair security header extraction with Extract CSP Directives and Extract HSTS Directives.
Compare response context
Use Extract HTTP Header Names, Extract CORS Headers, and Extract Cache Validator Headers.
Clean copied rows
Send extracted rows to Remove Duplicate Lines, Sort Lines, or Normalize Whitespace.
Quick answer
Extract Security Headers is a browser-based extract security headers for checking copied developer data such as payloads, URLs, encoded values, identifiers, snippets, or logs without sending the input to a server.

What this tool does
Extract Security Headers scans pasted HTTP response examples for headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, Referrer-Policy, Permissions-Policy, COOP, COEP, CORP, and Clear-Site-Data, then returns a copy-ready list with source-line context.
Common use cases
Extract common HTTP security headers from pasted response headers, CDN notes, deployment logs, and security-review snippets locally without fetching live sites.
Use Extract Security Headers when you are working with copied API payloads, logs, encoded values, config snippets, identifiers, or debugging data and need a quick browser-local check before pasting the result into docs, tickets, tests, or another developer tool.
How to use it
- Paste copied response headers, support tickets, deployment logs, CDN notes, or documentation snippets.
- Choose whether duplicate rows should be removed and whether output should be normalized for comparison.
- Review extracted security header rows, then copy the clean list for release QA, documentation cleanup, security-review notes, or incident handoffs.
Example workflow
Copy a small payload or encoded value from an API response, request URL, log line, or config file. Run the focused check here, confirm the output is readable, then continue with related developer data tools such as validation, formatting, decoding, timestamp conversion, or CSV/JSON conversion.
Privacy note
Extract Security Headers runs locally in your browser. It does not crawl, fetch, replay requests, upload, store, or log pasted headers. Redact production tokens, cookies, and private examples before sharing output.
