JWT Decoder — Decode & Inspect JWT Tokens Online

Decode JWT Tokens Instantly

Inspect the header, payload, and claims of any JWT token — essential for API debugging.

How to Use

  • Open the JWT Decoder tool
  • Paste your JWT token
  • See decoded header and payload
  • Check expiration status and claims
  • What You'll See

    • Header — algorithm and token type
    • Payload — user data, roles, expiration
    • Expiration status — is the token still valid?

    FAQ

    Does this validate the signature?

    No — signature validation requires the secret key, which should never be shared client-side.

    Is it safe to paste my JWT here?

    Yes — for this decoder, decoding runs in your browser; your token is not sent to our servers.

    What about expired tokens?

    The tool shows the expiration timestamp and whether the token is currently expired.
