Thanks for taking interest in GroupDocs.Viewer. Please note that GroupDocs.Viewer is a back-end, UI-less API which allows you to render the document as PDF document or in the form of HTML pages or images. When you render a document in HTML based rendering or image-based rendering, each page of the source document is converted into an HTML page or an image file. You will have to create your own front end application to view/display the HTML pages or images rendered by GroupDocs.Viewer.
