Stands for "Portable Document Format." PDF is a file format designed to present documents consistently across multiple devices and platforms. It was developed by Adobe 1992 and has since become one of the most widely used formats for saving and exchanging documents.
A PDF file can store a wide variety of data, including formatted text, vector graphics, and raster images. It also contains page layout information, which defines the location of each item on the page, as well as the size and shape of the pages in the document. This information is all saved in a standard format, so the document looks the same, no matter what device or program is used to open it. For example, if you save a PDF on a Mac, it will appear the same way in Windows, Android, and iOS.
The PDF format also supports metadata, such as the document title, author, subject, and keywords. It can store embedded fonts so you do not need to have the appropriate fonts installed to the view the document correctly. PDF documents may also be encrypted so only authorized users can open them.
