JWT Decoder

Decode and inspect JSON Web Tokens (JWT) easily. All decoding is done in your browser — your tokens never leave your device.

Why Use a JWT Decoder?

  • Debugging: Easily view and verify token payloads and metadata.
  • Transparency: Understand what information is being sent and stored in the JWT.
  • No Risk: Client-side decoding ensures your tokens never leave your browser.
  • Token Audits: Quickly inspect tokens from third-party services or APIs.

Tips for Secure JWT Handling

  • Do not share JWTs in public or untrusted platforms.
  • Check for token expiration and audience claims to avoid misuse.
  • Store sensitive tokens in secure storage (e.g., HttpOnly cookies).
  • Do not trust a JWT just because its decoded — always verify its signature on the backend.
