What this tool does
Cookie Parser only processes Cookie Header text actively pasted by the user. It separates each name and value by a semicolon and only splits at the first equal sign, thus preserving the equal sign within the value; the page cannot and does not cross-site read other website cookies.
- Preserves the original value and displays the Decoded Value when it is safe to decode.
- NULL values and values containing equal signs are not accidentally discarded.
- Document.cookie is not read, input is not saved, and network requests are not initiated.
How to use it
- Paste the Cookie Header text.
- Click "Parse Cookies".
- Check each Name, Raw Value and Decoded Value.
- When finished, click "Clear" to remove sensitive content.
Common uses
- Check the Cookie header in the development environment request.
- Compares the URL-encoded value to the human-readable value.
- Troubleshoot parsing problems caused by empty cookie values or equals signs within values.
Privacy and security
The Cookie Header is only parsed in the memory of the current page and does not read cookies from other websites in the browser, nor does it persist input.
Cookie Parser Features
Parses the pasted Cookie Header and displays the original value and secure decoding results side by side. Useful for everyday development and debugging; results can be reviewed, copied, or downloaded immediately.
FAQ
Can it read my cookies from other websites?
No. The browser's same-origin policy prohibits cross-site reading, and this tool only parses the text you pasted.
Why are Raw and Decoded Value displayed at the same time?
This preserves the true transmission value and allows you to view it in a readable form without overwriting the original text.
Will cookies be saved?
No, the page does not write input to localStorage or send it to the server.
Will values containing an equal sign be truncated?
No, the parser only splits the name and value at the first equal sign.
