About JWT Parser

This free JWT parser tool helps you decode JSON Web Tokens (JWTs) and JSON Web Encryption (JWE) tokens to inspect their components instantly.

Security Note: Our JWT decoder processes everything client-side. No tokens are sent to servers, ensuring your data remains completely private and secure.

Supports both JWS tokens (3 parts: Header, Payload, Signature) and JWE tokens (5 parts: Header, Encrypted Key, IV, Ciphertext, Authentication Tag).

JWT Decoder Features

JWT & JWE Support: Parse both JWS and JWE tokens instantly
Header Analysis: View algorithm, token type, and encryption details
Payload Inspection: Examine claims, expiration, and custom data
Token Status: Check if tokens are valid, expired, or not yet valid
Copy Functionality: Easy copy-to-clipboard for all sections
Client-Side Security: No data transmitted to external servers

Frequently Asked Questions

What are JWT and JWE tokens?

JWT (JSON Web Token) is an open standard for securely transmitting information between parties. JWE (JSON Web Encryption) provides encryption for sensitive data. Both are commonly used for authentication and secure data transmission in web applications.

Is this JWT & JWE parser safe to use?

Yes, our parser is completely safe. All token parsing happens locally in your browser - no data is sent to our servers or any third parties, ensuring your sensitive information remains private.

What's the difference between JWT and JWE?

JWT (3 parts) contains signed but readable data for authentication. JWE (5 parts) encrypts the payload for sensitive data protection, making it unreadable without the proper decryption key.

Can this tool decrypt JWE tokens?

This tool decodes JWE structure and shows components (header, encrypted key, IV, ciphertext, auth tag) but doesn't decrypt the payload, as that requires the secret encryption key.

What algorithms are supported?

Our parser supports all standard JWT/JWE algorithms including HS256, RS256, ES256 for JWT, and RSA-OAEP, A256KW, A256GCM, dir for JWE, plus many more encryption and signing algorithms.
