JWT Decoder

Decode a JSON Web Token to inspect its header, payload, and expiry.

Decode and Inspect Any JWT — Locally

CipherForces JWT Decoder splits a JSON Web Token into its three parts (header, payload, signature), base64url-decodes each, and pretty-prints the JSON with syntax highlighting. Expiration and issued-at timestamps are shown as human-readable UTC alongside a relative time ("expires in 14 minutes" / "issued 3 hours ago").

Unlike jwt.io — which is excellent but requires a network round trip to their servers — this tool runs 100% in your browser. You can paste production tokens without worrying that they'll leak into anyone's logs.

What It Shows

Header: The algorithm (alg) and token type (typ), plus any custom header claims.
Payload: Every claim in the token body with the standard ones (iss, sub, aud, exp, iat, nbf, jti) highlighted.
Expiry status: Clear green/yellow/red indicator — active, expiring soon, or expired.
Signature warning: If alg is "none", we flag it loudly. Unsigned JWTs should almost never be trusted in production.

Key Limitation

This tool does not verify the signature — that requires the issuer's public key or HMAC secret, which we don't ask for. Pasting a token into a decoder on any site is safe; pasting it into a verifier means handing over your secret. For debugging, decoding is usually all you need.

Privacy: All decoding happens in your browser. The token string is never sent to any server.
