Cookie Parser
v1.0.2Decode and inspect browser cookie strings.

How to use- →Paste a raw Set-Cookie header value into the input field and click Parse.
- →Review the decoded attribute table to check expiry dates, SameSite policy, and security flags.
- →Use the encoder panel to build a valid Set-Cookie header string from individual attribute inputs.
- →Try the preset examples to see how short-lived session cookies differ from long-lived persistent ones.
