A PDF reader is a software application designed to open, view, and interact with files in the PDF (Portable Document Format). These readers allow users to read documents while preserving the original formatting, making them ideal for sharing files across different devices and operating systems. Many PDF readers also offer features like text search, annotation, and printing.
Popular PDF readers include Adobe Acrobat Reader, Foxit Reader, and SumatraPDF. Some web browsers, like Google Chrome and Mozilla Firefox, also have built-in PDF reading capabilities. These tools are essential for anyone who frequently works with digital documents, ensuring easy access and usability.
