How to use this tool

Tokens are only decoded, never verified. Do not paste production secrets. Expiry uses the exp claim when present.

JWT decoder that never sends the token

JSON Web Tokens show up in Laravel Sanctum-like APIs, SSO and mobile apps. Decoding a token locally lets you read claims, expiry and the algorithm without pasting a production bearer token into a random website.

This page Base64-decodes header and payload only. The signature is displayed as “not verified” on purpose: verification needs the secret or public key, which you should not paste into a shared browser if you can avoid it.

Check exp, iat, iss and alg. A token with alg none or a date far in the future is a smell. Pair this with the HMAC tool only on non-production secrets.

JWT Decoder is built for everyday text, encoding and debugging. Decode JSON Web Tokens without sending them anywhere. View header, claims, issued-at and expiry times. Signatures are not verified. Because processing is local, you can paste staging tokens, draft SQL or unpublished copy without sending it to an unknown formatter.
