JWT Decoder — decode JSON Web Token online
Decode the header, payload, claims and expiry of a JSON Web Token. The token is parsed in your browser and never transmitted — safe for real tokens.
Token
How it works
1
Paste your input
Drop in the JSON, token, string or value you are working with.
2
Read the result
Output appears immediately, with errors pointed at the exact position.
3
Copy it out
Everything runs locally, so it is safe to paste a token or a key you would not upload.
