Regarding yo your question, yes, you can download your form as HTML, here is a guide that will help you to get the source code of your form: How-to-get-the-Full-Source-Code-of-your-Form
But all changes made in the form builder will not be reflected in your embedded form, you will need to get the source code again if you want changes made in the form builder to reflect in your form.
