PDF files are portable document format files, originally developed by Adobe Systems Inc. Each PDF file has a complete description of a fixed-layout flat document, including the text, fonts, graphics, and other information needed to display it. PDF files are the most popular way of distributing documents online because they retain the originality of the document no matter in which application or operating system you open them. Sometimes we come across PDF files which are feature restricted. If a PDF file is feature restricted then you may not be able to print it or copy text or pictures from it. But there are many free online services using which you may be able to remove these restrictions from your PDF files. Here are some of them :
