PDF stands for "Portable Document Format". It is a file format that was developed by Adobe Systems and is used to display documents across platforms and independently of the software or operating system used. This means that a PDF document can be opened and displayed on any device or computer without the need to install special software or fonts.
PDF files play an important role in the field of graphic design, as they make it possible to create and exchange print-ready files. Graphic designers use PDF files to share their designs and layouts with clients, printers and other project stakeholders. This is particularly important as PDFs offer higher print quality and colour fidelity than other file formats such as JPG or PNG.
Graphic designers can also use PDFs to present or archive their work. For example, if a designer wants to showcase their work online, they can create a PDF file containing a collection of their best work. This file can then be easily downloaded and viewed on different devices or platforms.
