JWT Decoder
Decode a JSON Web Token header and payload locally without sending the token to a server. Free to use online with no sign-up.
The tool only decodes JWT data; it does not verify the cryptographic signature.
Frequently asked questions
- Is JWT Decoder free to use?
- Yes. The tool is free to use and does not require an account.
- Is my input stored?
- Browser-based tool inputs normally stay on your device. Tools that rely on an external reference-data service, such as currency exchange, request only the information needed for that lookup.
