Frequently asked questions
Why can this page not read Facebook cookies with one click?
Browsers isolate cookies between websites, and ordinary webpage scripts cannot read HttpOnly cookies. Export your own cookies with a browser extension you trust, then process the exported data locally here.
Does a complete cookie format mean the account can sign in?
No. This tool only checks format and field completeness. It does not sign in to Facebook or verify whether a cookie is expired, invalid or revoked. Confirm your session on the official Facebook website.
Are cookies uploaded or saved by the website?
Input, parsing and conversion happen inside this browser. Cookies are not uploaded, and the input and output are not written to browser storage. Clear sensitive content before closing the page.
