JWT Decoder
Inspect the header and payload of a JSON Web Token locally. Decoding does not verify its signature.
Decoded content is untrusted until the token signature and claims are verified by your application.
Decode JWT headers and payloads
A JSON Web Token commonly contains a Base64URL-encoded header, payload and cryptographic signature separated by periods.
Reading the header and payload does not prove the token is authentic. Secure applications must validate the signature, issuer, audience and time-based claims.
