JWT Decoder
Decode and inspect JSON Web Tokens (JWT) locally. See exactly what your headers and claims contain.
The header typically consists of two parts: the type of the token, which is JWT, and the signing algorithm being used.
The payload contains the claims. Claims are statements about an entity (typically, the user) and additional data.
About this jwt decoder tool
Decode and inspect JSON Web Tokens (JWT) locally. See exactly what your headers and claims contain. iTryTools keeps the workflow simple so developers, analysts, and technical writers can finish common tasks without creating an account, installing desktop software, or uploading files to a separate conversion service.

Helpful tips
- Treat decoded tokens as sensitive because payloads can include account or session details.
- Remember that decoding a JWT does not verify whether its signature is trusted.
- Paste a small sample first if you are working with unfamiliar data.
- Review the generated output before using it in production code or documentation.
