The PDF format is one of the most common formats currently used on the internet. It's used to distribute documents, forms, images, and other content online. You can use a PDF viewer to open a .PDF file on your computer or mobile device.

Adobe Reader is the most popular tool for viewing .PDF files because it supports many features including text extraction and annotation which you cannot do with other viewers like Foxit Reader or Adobe Acrobat Reader Pro (which are popular alternatives).
