About
The XAVERT JWT Decoder decodes standard three-part JSON Web Tokens directly in your browser.
Main Features
- Decode Base64URL JWT header and payload segments.
- Handle UTF-8 and Unicode JSON content correctly.
- Inspect algorithm, expiration and issued-at claims.
- Detect expired and not-yet-valid tokens from timing claims.
- Copy token, header, payload or the complete decoded result.
- Download decoded JWT data as JSON.
Signature Verification
This tool decodes JWT data only. It does not verify the cryptographic signature and therefore cannot establish that a token is authentic.
Privacy First
Everything is processed locally within your browser. Your JWT tokens and decoded data are never uploaded, transmitted, shared or stored on any server.
