Decode & Understand
Your Tokens
Fast, private developer tools for decoding, inspecting, encoding, and formatting token data directly in your browser.
Paste a JSON Web Token to inspect its structure and contents directly in your browser.
Popular Tools
JWT Decoder
Instantly decode JSON Web Tokens to view their Header, Payload, and Signature structure in a clean, color-coded UI.
JWT Inspector
Analyze token metadata. Calculates expiration timers, clock skew, and surfaces unknown custom claims for security auditing.
Base64URL Decoder
Safely decode unpadded Base64URL strings (RFC 4648) into raw UTF-8 text or view binary hexadecimal representations.
Base64URL Encoder
Encode Unicode strings, JSON blobs, and arbitrary text into web-safe, unpadded Base64URL structures.
Token Formatter
Minify massive JSON payloads, pretty-print deeply nested objects, and auto-format raw unpadded JWT strings.
Token Generator
Craft custom unsigned mock JWTs for local backend testing with integrated expiration injection helpers.
Why TokenDecode?
Privacy-Focused Architecture
All of our tools are built using client-side JavaScript. Processing happens locally in your browser to ensure your sensitive token contents are never uploaded to a backend server.
Fast Developer Workflow
We removed the friction. No login, no accounts, and no bloated UIs. Just paste your token and get instant insight into its headers, payloads, and timestamps.
Simple Interface
Built meticulously using the Stitch design system, TokenDecode offers a clean, distraction-free environment tailored specifically for developers debugging authorization systems.

100% Client-Side Processing
TokenDecode is designed with a privacy-first architecture. When you paste a token into our tools, it is processed directly in your browser's memory. We do not transmit, log, or store your tokens.
