JWT Decoder
Decode and inspect JSON Web Tokens (JWT) to view header, payload, and signature.
About JWT
- • JWT (JSON Web Token) consists of 3 parts: Header, Payload, and Signature
- • This tool only decodes the token - it does NOT verify the signature
- • Never share JWTs containing sensitive information
- • All decoding happens in your browser (client-side)
🔒 Your data never leaves your browser - all processing happens locally
