PDF (Portable Document Format) is a file format that has captured all the elements of a printed document as an electronic image that you can view, navigate, print, or forward to someone else. PDF files are created using Adobe Acrobat , Acrobat Capture, or similar products.
PDF files are Compatible Across Multiple Platforms. A PDF format represents a document independently of the hardware, operating system and application software used to create the original PDF file. It was designed to create transferable documents that can be shared across multiple computer platforms.
PDF format has the big advantage of compressing high-quality files to a relatively small file size. That's ideal for saving hard drive space, particularly if you're working with limited storage resources. The files can be protected by password.
PDF, as the name Portable Document Format implies, was developed by Adobe Systems as a means for digital file exchange. The main idea behind the file format is to enable all computer users to be able to open, review, and print the documents saved in it.
