JWT Decoder
Decode JSON Web Token headers and claims with expiry dates without sending tokens anywhere.
Decoding is NOT Signature Verification
This utility parses and base64url decodes the token claims purely inside your browser. No token is ever verified against a private key or transmitted across the network. Avoid pasting active production session credentials.
