JWT URL Decoder

Detects JWTs in the current tab's URL and decodes them locally.

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.
