Adobe Acrobat Reader is a free software application developed by Adobe Systems. It is used to view, sign, and annotate PDF documents. PDF stands for Portable Document Format, which is a file format that preserves the fonts, images, graphics, and layout of any source document. This means that PDF documents look the same on any device, whether it is a desktop computer, a laptop, a tablet, or a smartphone.
