Paste headers copied from DevTools, cURL -v output, or a raw HTTP exchange. The parser normalizes them into name-value pairs, explains what well-known headers mean, and exports them as JSON for use in code.
Common uses
- Understand a response's caching behavior at a glance
- Check which security headers a server sends
- Convert copied headers into a JSON object for fetch or Axios
