Decode JWT Token Online
JSON Web Tokens carry claims between APIs and auth systems. Decoding helps debug expiry, roles, and issuer — but never paste production secrets into untrusted sites.
What you'll see
- Header (alg, typ)
- Payload (sub, exp, custom claims)
- Signature (verified only with secret)
