Mac FlipViewer is a FlipBook® Viewer that lets you view objects, such as web pages, albums, manuals, catalogs (collectively called Books) created using FlipPublisher®, FlipAlbum® or any products that create OEB Package Format files (OPF). Every page of the book is only a click away. While you are reading the current page, the next few pages will be streamed into your PC. FlipBooks can be sent as small attachments via emails. FlipBooks can also contain full-page advertisements along with the regular banner advertisements.
