JWT Decoder

Decode JWT headers and payloads locally in your browser. Inspect claims, expiry, issuer, and timestamps without sending tokens anywhere.

🔒 Zero network requests. Tokens never leave your browser.

Frequently Asked Questions

Does this verify the JWT signature?

No. This page only decodes the header and payload locally. It does not validate signatures or trust the token.

Why use this instead of jwt.io?

TeaFun emphasises privacy-first decoding. Your token stays in your browser and is never uploaded for processing.

What timestamps are shown?

If present, exp, iat, and nbf are converted from Unix timestamps into readable ISO dates.
