Decode and Inspect JWT Tokens
Decode the header and payload sections of a JSON Web Token (JWT) to inspect its claims.
JWT tips
JWTs have three parts separated by dots: header.payload.signature. Each part is Base64URL encoded. Decode the first two to inspect claims.
Base64URL differs slightly from standard Base64: - replaces +, _ replaces /, and padding (=) is omitted. The decoder handles this automatically.
Never decode a JWT on an untrusted public tool if it contains sensitive data. This tool processes everything locally in your browser.
The payload contains exp (expiry), iat (issued at), and sub (subject) claims as Unix timestamps. Convert them to see exact expiry dates.
