About This Tool

The JWT Parser decodes the Header and Payload of a JSON Web Token locally in your browser, displaying the signing algorithm, issued-at time, expiration, and other claims. Ideal for debugging authentication flows or checking whether a token has expired. Note: this tool decodes tokens but does not verify signatures.
