PDF

A .PDF file is a multi-platform document file created by Adobe Acrobat or another PDF company. It is used for saving documents and publications in a standard format that can be viewed on multiple platforms, such as a computer or a phone. In many different cases, PDF are created from existing documents, instead of from scratch.

PDF files are used in many different ways, such as a part of a school project. The file can contain text, images, formatted code, annotations, outline, and other document-related data.
