Decode JWT header and payload locally. No token leaves your browser.
⚠️ Decoding runs 100% locally in your browser — your JWT is never uploaded. Never paste production access tokens or sensitive credentials into any online tool. This decoder only reads the header and payload; it does NOT verify signatures and must not be used to trust token contents.
