JWT Decoder

Decode and view JWT token contents

Free JWT token decoder. Decode JSON Web Tokens to view header, payload, and signature information.

💡 About JWT Tokens

  • JWT (JSON Web Token) consists of three parts: Header, Payload, and Signature
  • Header contains token type and signing algorithm (e.g., HS256, RS256)
  • Payload contains claims (data) about the user or entity
  • Signature is used to verify the token hasn't been tampered with
  • Common claims: iss (issuer), sub (subject), exp (expiration), iat (issued at)
  • This tool decodes tokens but does not verify signatures (requires secret key)
