What is PDF?

Definition

A PDF is a document file type designed to preserve the appearance and layout of a document across different devices and software. Text, images, formatting, and page structure remain consistent regardless of where the file is opened or viewed. This makes PDFs well suited for sharing documents that are intended to be read, reviewed, or printed without altering their appearance.
