JWT Decode Tool - Decode and View JWT Token Contents
Characters: 0 | Bytes: 0
ABOUT
This page provides a specialized tool for decoding JWT (JSON Web Token) tokens. JWTs are a compact, URL-safe means of representing claims between two parties. They are commonly used for authentication and authorization in web applications.
The JWT Decode tool helps you view the contents of a JWT token by decoding its three parts: the header, payload, and signature. The header contains metadata about the token, the payload contains the actual data (claims), and the signature is used to verify the token's authenticity. This is particularly useful for debugging authentication issues or understanding what data is being transmitted in your JWT tokens.
As part of StringFlux, this tool can be chained with other operations for more complex transformations. For instance, you can decode a JWT token and then format its payload as JSON, or encode the decoded data to Base64. The tool is especially helpful when working with authentication systems, API development, or any application that uses JWT tokens.
FEATURES
Transformation Chains

Context menu supports copy text selection to a new editor. Useful to apply transformations to a specific part of a string.
Privacy First
All string transformations happen purely on the browser side, ensuring your data never leaves your device.
Intuitive UX
Simple and intuitive UX to provide operation in 3 ways: recommended by content type, search and category.
