How to use the JWT Decoder?

A JWT Decoder allows you to decode a JSON Web Token and view its readable contents. It displays the token’s header and payload in a clear and structured format.

Simply paste your JWT into the decoder and start the decoding process. The tool separates the token into its components and decodes the header and payload for easy inspection.

You can view the decoded header and payload, including claims such as the issuer, subject, expiration time, and other information contained in the token.

No. Decoding a JWT only reveals its encoded contents and does not verify whether the token is authentic or has been modified. Signature verification requires the appropriate signing key.

No. CodeLiqo’s JWT Decoder processes your token directly in your browser. Your JWT does not need to be uploaded to a remote server for decoding, helping keep your data on your device.
