JWT Decoder

Developers frequently need to inspect the contents of an authentication token during API development and debugging. Our client-side decoder makes this instant and secure.

• 1Paste the Token: Simply copy your Base64Url encoded JWT (which typically looks like three long strings separated by dots) and paste it into the left input box.
• 2View the Claims: The token is instantly parsed and split into its three components. The Header and Payload are pretty-printed as syntax-highlighted JSON on the right side.
• 3Copy the Payload: If you need the raw JSON data, just click the "Copy Payload" button next to the Payload section.
