Does this verify the signature?

No. Decoding tells you what the token says, not whether it's authentic. To verify, use your server-side library with the issuer's public key.

Is my token sent anywhere?

No. Decoding happens entirely in your browser. The token never leaves your device.

About this tool

JWT Decoder

Decode a JSON Web Token to inspect its header and payload. Does not verify the signature.

Paste a JWT (three dot-separated base64url parts) and view its header and payload as formatted JSON. Highlights common timestamp claims (iat, nbf, exp) as human-readable dates and flags expired tokens. Decoding is NOT verification — it tells you what the token says but not whether the signature is valid.
