About TokenDecode

What is TokenDecode?

TokenDecode is a suite of lightweight, browser-based utilities designed for developers working with JSON Web Tokens (JWT) and Base64URL encoding. Our tools make it simple to decode, inspect, format, and generate unsigned token payloads during development and debugging.

Why it exists

Modern web development relies heavily on bearer tokens and stateless authentication. However, inspecting the contents of these tokens often requires developers to paste sensitive access tokens into random third-party websites that may log or store them on a backend server. We built TokenDecode to solve this problem by providing a comprehensive suite of utilities that execute entirely within your browser.

Privacy-First Architecture

All TokenDecode tools are implemented using client-side JavaScript. When you paste a token into the JWT Decoder, Token Formatter, or any other utility, the data never leaves your device. We do not transmit your input to an API, we do not log your payloads, and we do not store your tokens in analytics. This ensures that you can safely debug integration environments without worrying about accidental credential exposure.

Designed for Developers

Our interface is intentionally stripped down. You won't find aggressive popups, forced account registrations, or bloated UI components. TokenDecode is built to be fast, responsive, and out of your way. Features like chromatic token dissection, automatic JSON prettification, and precise timestamp calculations are built to save you time.
