Cookie Decoder

What the cookie decoder shows

Paste a Cookie header (what the browser sends) or a Set-Cookie header (what the server returns) and the tool splits it into name, value, Expires/Max-Age, Domain, Path and the Secure, HttpOnly and SameSite flags. URL-encoded and Base64 values are shown decoded.

Why it matters when using proxies

For scraping and multi-account work, cookies are how a site ties a session to an IP address. A cookie issued under one IP and replayed from another is a classic anti-fraud trigger. The decoder shows which cookies carry the session, when they expire and whether they travel over plain HTTP. Keep sessions stable with GProxy sticky residential proxies — one IP for the whole cookie lifetime.

FAQ

Is my data sent to a server? No, parsing runs entirely in your browser.

Cookie vs Set-Cookie? Set-Cookie carries attributes (expiry, domain, flags); Cookie only carries name=value pairs.
