A PDF file is a type of file format developed by Adobe in the 1990s to present documents, including text formatting and images, in a manner independent of application software, hardware, and operating systems. PDF files can contain not only images and text, but also interactive buttons, hyperlinks, embedded fonts, video, and more.
