About
Converts locally among HTTP Cookie headers, JSON arrays, and Netscape cookies.txt.
How to use
Paste any supported format, then export JSON, HTTP, or Netscape.
What this tool does
Converts three common cookie text formats so you do not edit separators by hand.
Input and output examples
HTTP headers look like name=value; session=abc. You can also paste a JSON array or a Netscape file.
Common uses
Turn cookies copied from a browser into cookies.txt, or into JSON for editing.
Limits and privacy
Cookies may include a login session. Only process your own data locally, then clear it.
FAQ
Why is the format unrecognized?
Mixed formats, missing fields, or not one of the three types. Compare with the examples.
Are cookies sent to the server?
No. Conversion stays in the browser.
Where is Netscape format used?
Some downloaders and older tools read cookies.txt. Confirm the target actually needs it.
