Free tool · token never leaves your browser
JWT Inspector
Decodes a JSON Web Token and highlights the claims that matter for Entra and OAuth debugging: tid, scp, roles, aud, exp, and more. Decode only; the tool never verifies the signature and never transmits the token.
Decoding happens entirely in your browser with no network calls. This tool does NOT verify the signature — a decoded token is not a trusted token. Never paste a production token you would not want in your own browser history.
