You might be surprised just how quickly your large PDF files open and pages smoothly refresh as they are scrolled. Add Comments and Annotations to any PDF file (subject to security settings) - unlike the Adobe Viewer which requires the PDF creation tool to be 'certified' by Adobe! Add & apply Custom Stamps from any Image or PDF File and even your Windows Clip board! Mark-up pages with text and objects. Type directly on any PDF page, not just Adobe enabled forms documents - in Typewriter mode. Export PDF pages or entire files to any one of the supported Image formats including BMP, JPEG, TIFF, PNG and many more. Extract text from a PDF page/File.
