You wouldn’t know it by the state of things, but Adobe Reader isn’t the end-all, be-all of PDF. Standing for "Portable Document Format," PDF is a file format used to maintain the uniform appearance of a document no matter what type of hardware or software is being used to view it. You will see it used frequently for government documents such as IRS and court forms, job applications, ebooks and more since it looks the same everywhere. Adobe may have created the PDF format, but they made it a free-for-all file format in 2008, resulting in software for reading and creating PDFs that rival Adobe’s own.
You might be asking yourself ,“Why would I want to switch from Acrobat Reader?” Over the years Adobe Reader (once known as Acrobat Reader) has become a horribly bloated program that takes entirely too much space on your hard drive and, in my opinion, an unacceptable amount of RAM to use. It’s slow to load and slower to use. Furthermore, Adobe is constantly releasing updates for the program; it seems like every other time I turn on my Windows 7 computer there’s a notification for an Adobe Reader update, and I’m growing tired of it.
