Frequently Asked Questions

What cookie fields are parsed?

Name, value, domain, path, expires/max-age, secure flag, HttpOnly flag, SameSite attribute, and other Set-Cookie directives are extracted and displayed.

Can I check security flags?

Yes. The tool analyzes Secure, HttpOnly, SameSite, and domain settings, flagging missing or insecure configurations.

Does it detect expired cookies?

Yes. If a cookie has an Expires attribute in the past, the tool flags it as expired. It also shows max-age countdown for session cookies.

Can I parse multiple cookies?

Yes. Paste multiple Set-Cookie headers and the tool parses each one separately, displaying structured data for every cookie.

Is my cookie data uploaded?

No. All parsing happens locally in your browser. No cookie data is transmitted to any server.
