JWT Decoder — claims
Decode and inspect JSON Web Tokens (JWT). View header, payload, and signature without verification.
How to use JWT Decoder
Paste Your JWT Token
Click the text input field labeled 'Enter JWT Token' and paste your complete JSON Web Token. The token should contain three parts separated by dots (header.payload.signature). Ensure you copy the entire token without any extra spaces or line breaks.
View Decoded Results Instantly
The decoder automatically processes your token and displays three sections below: Header (algorithm and token type), Payload (claims and user data), and Signature (verification string). Each section is formatted as readable JSON with syntax highlighting for clarity.
Copy or Export Decoded Data
Click the 'Copy' button next to any section to copy decoded data to your clipboard. Use the 'Export' button in the top-right corner to download all three sections as a JSON file for documentation or sharing with team members.
