JWT Decoder
developerPopularDecode JSON Web Tokens locally to inspect headers, payload claims, and token expiration.
Decoded locally. Decoding does not verify the signature.
Offline Ready•Zero Uploads
Decoded locally. Decoding extracts readable claims without validating the cryptographic signature. Never paste sensitive production tokens on untrusted networks.

Frequently Asked Questions
No. Decoding parses base64 claims without sending your secret key over the wire. Signature verification requires the private or HMAC secret.
