WHAT IS A PDF FILE?
PDF (Portable Document Format) is a file format created by Adobe Systems Inc to enhance document exchange. Documents in PDF are independent from device and display resolution and can be read on any operating system (Windows, Macintosh, Linux). These files are a combination of vector graphics, text, and raster graphics. They support links (internal and external), forms, javascript and 3D objects. PDF documents may have different levels of encryption (view, print, select…) and even DRM.
Since the 90’s, Adobe’s PDF has become the standard file format for document exchange.
