What Is a PDF Reader? – A PDF reader is an application designed specifically for working with PDF files, the universal standard for sharing documents that look the same on any device. It handles everything from simple viewing to basic interactions like searching text or filling forms.

- Many allow annotations, highlighting, or digital signatures without changing the original document.
Modern readers work across operating systems and often include cloud integration for easy access.
