Portable Document Format, abbreviated PDF, is a type of file format used to represent documents with no dependency on the computer software and hardware, or the OS.
Every PDF doc contains a comprehensive description of a fixed-layout flat document and information needed to display it, such as the fonts, graphics, and text.
John Warnock, the co-founder of Adobe Systems, has developed in 1991 a system named Camelot, that later will evolve and became the PDF we know today.
PDFs may include multiple types of content besides flat text and graphics, such as annotations, form fields and other interactive elements, layers, rich media, and more.
Other great PDF features include digital signatures, encryption, the possibility to attach files and metadata to enable workflows requiring these features.
