JWT decoder
Decoding and verification happen entirely in this page. The token, the secret and the key are never sent anywhere — this tool makes no network requests after it loads.

Paste a token and a key, then press Verify. Nothing leaves the page.
Why this page has no analytics or ads. People paste live tokens into
decoders every day. A token is a credential until it expires. This page loads no
third-party script of any kind, so there is nothing here that could read what you paste.
