Decoded only. The signature has not been verified; these claims do not establish trust or validity.
Updates as you type or change an option
Inspect a JWT header and payload separately, and read issued-at, not-before and expiry claims as UTC dates.
Paste a JWT with three dot-separated parts. The header and payload are formatted as JSON and can be copied separately. Numeric iat, nbf and exp claims also appear as UTC dates.
This tool does not verify the signature, issuer, audience or revocation status. Anyone can alter unverified claims, so the display does not establish that a token is trusted or valid. Tokens remain in page memory. Input limit: 128 KiB.
