• HTTP is unsecured while HTTPS is secured.

• HTTP sends data over port 80 while HTTPS uses port 443.

• HTTP operates at application layer, while HTTPS operates at transport layer.

• No SSL certificates are required for HTTP. with HTTPS it is required that you have an SSL certificate and it is signed by a CA.

• HTTP doesn't require domain validation, where as HTTPS requires at least domain validation and certain certificates even require legal document validation.

• No encryption in HTTP, with HTTPS the data is encrypted .
