About This Tool

Decode JWT headers and payloads locally. Paste a dot-separated JSON Web Token.

Good to know

Decoding does not verify the signature. Never treat a decoded claim as authentic without server-side verification.

Worked Example and Result Check

Decode a JWT header and payload to inspect claims and expiration time.

Decoding does not verify the signature, so displayed claims are not proof of authenticity.
