Viewing PDFs with PDF-XChange Viewer Portable is fast and smooth; you can skip through pages, view documents in a variety of layouts, and search and find both pages and keywords seamlessly. PDF-XChange Viewer Portable's toolbars are entirely customizable, and there is a considerable range of configuration options.
