Decode and inspect JWT (JSON Web Tokens) online. View header, payload and signature. Instantly parse expiration, issuer and claims. Free tool — tokens never sent to servers.
Your data never leaves your browserRelated
All decoding happens in your browser — your token is never sent to any server. However, be cautious with tokens that grant access to sensitive resources. Avoid pasting production tokens in shared environments.
This tool decodes the token (reads its contents) but does not verify the signature. Signature verification requires the secret key and should be done server-side.
