Decodificador de JWT
Decodifica el encabezado y el payload de un JWT, sin verificar la firma.
Esto solo decodifica el encabezado y el payload del token — no verifica la firma. Verificarla requiere la clave secreta o pública con la que se firmó el token.
Cómo usar esta herramienta

- 2
The header and payload decode automatically.
- 3
Copy either section, or inspect the claims directly.
Preguntas frecuentes
Does this verify the token's signature?+
No, it only decodes the header and payload — it doesn't check whether the signature is valid.
Is my token sent anywhere?+
No, decoding happens entirely in your browser; your token is never transmitted.
Can it decode expired tokens?+
Yes, it decodes the contents regardless of the expiry claim.
