JWT Decoder
JWT Token Decoder
Decode and inspect JSON Web Tokens
About JSON Web Tokens
- JWTs consist of three parts: Header, Payload, and Signature
- The header contains the algorithm and token type
- The payload contains claims (user data, expiration, issuer, etc.)
- This tool decodes tokens but does not verify signatures
- Never share tokens containing sensitive data - they are only encoded, not encrypted
- All processing happens locally in your browser
