Image To PDF can automatically clear and skew-correct black-and-white images. ImageToPDF can operate independently of Adobe Acrobat. If your application doesn't require Optical Character Recognition functionality, ImageToPDF allows you to compose electronic books which can then be issued to the Web. You can scan paper documents directly to image files and then convert them to PDF using Image To PDF.
