Welcome to the PDFBlink home page!

Welcome to the download page of PDFBlink - a visual comparator for PDF on MS Windows 2000/XP/Vista, Windows 7 and Windows 8. It allows you to view several PDF and visualize differences. It is especially useful for version control of large PDF pages like plans or diagrams.
