Overview of PDF Readers

PDF readers are programs that enable users to view, manipulate and print Portable Document Format (PDF) files. A PDF reader is the most basic component of a PDF workflow, as it allows a user to access and interact with all types of PDF content including text, images, multimedia elements and links.

Since its invention in 1993 by Adobe Systems Inc., the Portable Document File (PDF) format has become one of the most popular formats for creating electronic documents. This widely adopted standard allows documents to be securely shared across different platforms and systems. As a result, a variety of PDF readers have been developed over the years in order to make it easier for users to access and work with this type of file.

PDF readers come in several varieties such as web-based applications, desktop programs or mobile applications that can be downloaded from app stores or websites. Most modern web browsers are capable of opening PDF files within their own window without requiring any additional software with support for interactive features like zoom in/out and multi-page viewing. Some popular desktop apps include Adobe Acrobat Reader DC (formerly known as Adobe Reader), Foxit Reader for Windows and MacOS as well as Skim for MacOS. Mobile users have access to many dedicated apps from both Apple App Store and Google Play store including Adobe’s official mobile reader app called Acrobat Reader Mobile which offers an intuitive user experience tailored specifically for smartphones and tablets running iOS or Android operating systems respectively.

Besides being able to open basic PDF files and display them on screen, an ideal reader should also provide features like searchable text layer extraction and full text indexing which aids faster searching through large collections of documents; password protection which prevents unauthorized individuals from accessing confidential information; annotation tools that allow users highlight text passages or add notes directly on document pages; digital signatures which certify the authenticity of documents; form filling capabilities that supports data entry into interactive forms; “flattening” options that facilitate better printing results; cloud integration allowing documents stored online be accessed from anywhere using any device connected to the internet with up-to-date copies automatically synced between devices; social media sharing options enabling quick dissemination via popular networks such Facebook or Twitter etc.

Overall, choosing a suitable reader application depends on user needs since not all readers offer identical feature sets so it pays off to research the ones available before arriving at a decision as we need these versatile tools when working with digital documents today.
