In order to open a large PDF file and view it on yourputer or mobile device you should install a PDF reader such as Adobe Reader s for example. It by far the most popular tool for opening and reading PDFs and it not surprising because its developers invented the PDF back in 1993. This software is aponent of Adobe Acrobat s by Adobe Systems and it a free cross-platform program that can be downloaded from their website absolutely free of cost. Along with viewing printing and sharing PDF files this tool offers some other useful features like full-screen viewing web integration formpletion highlighting and sticky notes as well asmenting signing and certifying and more. It lacks the ability to create PDFs and edit existing or media so if you need software for creating manipulating and enhancing PDF documents you might consider Adobe Acrobat.

Why are portable document format (PDF) files so commonly used?
Because there is a business niche that PDF was created to fill 3 years ago that still exists and PDF is now so mature that it is unrivaled bypetitor formats. That niche is serving as a digital printout and a number of bordering uses. PDF main objective is precisely capturing the appearance of any document or output of any application; identically across platforms and immutably if need be. This original application spawned popularity and further feature development for professional printing archival paperless and secure business document workflows forms engineering and multimedia accessibility and many others. PDF was also the first such format adapted for Internet delivery (as was its apanying free viewer software Acrobat Reader). At the end of th 9s Adobe the creator of both worked with Netscape the then browser market challenger and innovator to develop the concept of plugins extending the browser's functionality to enable the seamless progressive display of PDF as it was being downloaded just like HTML pages. The Acrobat plugin was also downloadable for free. At the time there were no other ways to publish universallypatible and pixel-perfect replicas of carefully designed documents (or books and magazines) to the browser. That as well as PDF's adoption by the IRS in the US hugely contributed to the format's ubiquity and popularity.
