JWT Decoder
Decode JWT (JSON Web Tokens), including oauth bearer tokens. Save results and share URL with others.
What is this Tool for?
The JWT Decoder tool is designed to help you decode JSON Web Tokens (JWTs) quickly and easily. JWTs are compact, URL-safe tokens used for transmitting claims between parties. These tokens are commonly used in authentication and authorization protocols. With this tool, you can see the content of a JWT, including its header and payload, in a readable format.
JWTs often contain base64-encoded data in their header and payload sections. You can use the Base64 to Image Converter if the payload contains image data, or the Convert Query String to JSON tool to parse any query strings found within token claims. For formatting decoded JSON payloads, try the JSON Formatter.
How to Use the JWT Decoder
Follow these simple steps to decode your JWT:
- Paste your JWT token into the input field.
- Click on the "Decode JWT" button.
- View the decoded JWT information, including the header and payload, in a formatted manner.

Frequently Asked Questions
What is a JWT?
A JSON Web Token (JWT) is a compact, URL-safe token used for securely transmitting information between parties. It consists of three parts: the header, the payload, and the signature. JWTs are often used for authentication and authorization in web applications.
Why can't I see my JWT token decoded properly?
If your JWT token is not decoding properly, it might be due to an invalid format or incorrect token structure. Ensure that your token has three parts separated by dots ('.') and is a valid JWT. If the issue persists, verify the token's integrity and encoding.
Is my JWT data stored or shared when using this tool?
No, your JWT data is not stored or shared. The tool processes your token locally on your device and does not send any data to external servers. However, we recommend not entering sensitive information into the tool.
