About JWT Decoding
JSON Web Tokens (JWT) consist of three Base64URL-encoded parts separated by dots: header, payload, and signature. This tool decodes the header and payload without verifying the signature, allowing you to inspect the token contents.
- Decoding does NOT verify the token signature
- Anyone can decode a JWT - the payload is not encrypted
- Never put sensitive data in JWT payloads
- Use JWT Verify tool to validate signatures
- Check expiration times to ensure token validity
