JWT Decoder
Paste a JWT token to decode its header and payload locally — inspect expiry and claims. Nothing leaves your browser.
Perfect for developers debugging authentication issues, testing JWT implementations, or inspecting tokens from APIs. All decoding happens client-side - tokens are never sent to any server. The tool supports all standard JWT algorithms (HS256, RS256, ES256, etc.).
The interface highlights important claims like 'exp' (expiration), 'iat' (issued at), 'iss' (issuer), and 'sub' (subject). It warns if the token is expired or not yet valid. You can also verify the signature if you provide the secret key (for HMAC) or public key (for RSA/ECDSA).
This tool decodes JSON Web Tokens (JWT) directly in your browser. Paste any JWT (starting with 'eyJ...') and the tool instantly splits it into three parts: header (algorithm, type), payload (claims, data), and signature. Each section is pretty-printed as JSON for easy reading.
Paste any JSON Web Token to instantly decode the header, payload, and signature. Verify token structure, check expiration, and debug auth issues. Online JWT decoder and validator.
