PDF (Portable Document Format) has become one of the most widely used file formats for sharing and distributing documents. Over the years, PDF has evolved, with various versions being released to enhance its functionality and features. In this article, we will compare PDF version 1.7 and the new version 2, highlighting the differences and improvements.
