JWT Decoder
Paste a JSON Web Token to read its header and payload. Decoding happens in your browser and nothing is sent anywhere. This tool does not verify the signature, so do not trust a token only because it decodes.
How to use JWT Decoder
- Paste a JSON Web Token.
- Read the header, payload, issued and expiry times.
Does this verify the token?
No. It only decodes it. A token can decode fine and still be forged, so the signature must be checked on the server.
Is my token sent anywhere?
No. Decoding runs in your browser.
