About the Cookie Parser Online Free Tool

The Cookie Parser Online Free Tool separates a raw HTTP Cookie request header into readable cookie names and values. Paste the semicolon-separated header value to inspect individual cookies without manually splitting the string.

The parser runs locally in your browser. It treats each semicolon as the boundary between cookie pairs and uses the first equals sign in each pair to separate the name from the value. Cookies may contain sensitive session information, so use redacted or test values when possible.

How to Parse a Cookie Header

1. Copy the value of an HTTP Cookie request header.
2. Paste the header value into the input field without the leading Cookie: label.
3. Select Parse Cookie to list each recognized name and value.
4. Review the parsed pairs and the total number of cookies found.

Cookie Header Example

An input such as session=abc123; theme=dark; cart=4 produces three entries: session, theme, and cart, each with its corresponding value. A value may contain additional equals signs because only the first one separates the cookie name from its value.

What the Parser Does Not Do

The tool trims surrounding whitespace from names and values, but it does not URL-decode values or interpret their application-specific contents. It also does not parse Set-Cookie response attributes such as Expires, Domain, Path, Secure, HttpOnly, or SameSite.

Segments without a usable cookie name are ignored. If the same name appears more than once, the last parsed value for that name is kept in the report.

Cookie Parser FAQ

Can I parse a Set-Cookie response header?
No. This tool is designed for the combined Cookie request header, not response attributes.

Are encoded values decoded automatically?
No. Encoded characters remain encoded, although surrounding whitespace is trimmed.

Can a cookie value contain an equals sign?
Yes. Additional equals signs after the first one remain part of the value.

Is the cookie header sent to a server?
No. Parsing happens in your browser.
