JWT URL Decoder

JWT URL Decoder detects JSON Web Tokens in your current tab’s URL and decodes them locally in a convenient side panel. Inspect authentication redirects and token claims without copying sensitive tokens to an external website. Features: - Detects JWTs in URL query parameters, fragments, and paths. - Displays a toolbar badge when tokens are found. - Shows decoded headers, payloads, and expiration status. - Highlights common claims, including issuer, audience, and subject. - Supports multiple tokens in the same URL. - Provides copy buttons for token data. Privacy comes first: no network requests, analytics, or token storage. All decoding happens locally in your browser. JWT URL Decoder does not verify signatures or confirm token authenticity. It helps you inspect what a token contains.
