    Inspect JSON Web Tokens (JWT) with Ease

    Debugging authentication flows shouldn't be a mystery. Our JWT Decoder allows you to paste any JSON Web Token and instantly view its decoded Header and Payload claims. Check expiration times (exp), issued-at dates (iat), and user roles without needing the signing secret.

    Key Features

    • Full Token Breakdown: See Header, Payload, and Signature sections clearly.
    • Human-Readable Dates: Automatically converts Unix timestamps (exp, iat) to readable dates.
    • No Secret Required: Decodes base64 structure without verifying signatures (safe for inspection).
    • Client-Side Only: Your sensitive tokens are processed locally and never transmitted.
