What is a PDF File?
A PDF file, or Portable Document Format file, is a file format developed by Adobe Systems that can be used to represent documents in a format that is independent of the software, hardware, and operating system used to create or view it. PDF files can contain text, images, and other multimedia content, and they can be viewed, printed, and edited using a variety of software applications.
