Header
Header will appear here... Payload
Payload will appear here...How it works
Paste a JWT token to decode its three parts: Header, Payload, and Signature. The header and payload are Base64URL-encoded JSON objects.
- Header - Contains the algorithm (HS256, RS256, etc.) and token type
- Payload - Contains claims like subject, issuer, expiration, and custom data
- Signature - Used to verify the token (requires the secret key)
This tool only decodes tokens locally. It does not verify signatures.
