Step-by-step explanation:

The file extension PDF stands for Portable Document Format. It is a file format commonly used for documents that need to be shared and viewed by anyone, regardless of the software or hardware they are using.

PDF files preserve the layout and formatting of the original document, allowing it to be viewed and printed consistently across different devices and operating systems. It's a file format developed by Adobe Systems in 1993 for presenting documents in a manner independent of application software, hardware, and operating systems.

PDFs encapsulate a complete description of a fixed-layout flat document, including the text, fonts, vector graphics, raster images, and other information needed to display it.
