JWT Decoder
Decode and inspect JSON Web Token (JWT) payloads.
About the JWT Decoder
JWTs store identity and permission claims in Base64-encoded payloads. Our decoder splits the token into its three parts and pretty-prints the header and payload so you can inspect claims without any setup.
How to use the JWT Decoder
- Paste your JWT into the input.
- Header and payload are decoded and displayed.
- Note: We never send your token to any server.
Frequently Asked Questions
- Can I verify the JWT signature?
- Signature verification requires the secret or public key, which you should never share. This tool decodes only it does not verify.
