PDF-XChange Pro is actually a product suite that includes a PDF-XChange Standard, PDF-Tools & PDF-XChange Viewer PRO. Allowing both the creation (from Image file formats, Image Scanners/Web CAMS and text files etc) and manipulation of Adobe compatible PDF files, PDF-Tools is an ideal tool to compliment your existing PDF creation application or as a 'stand alone' tool in it's own right! PDF-Tools requires no additional 'plug-ins' or applications such as Adobe Acrobat or Distiller.
