As a Penn LPS online student, you may often work with PDF files as opposed to just Word documents.
While there are plenty of variants to the Adobe Suite, we suggest the free-to-use Adobe Reader. While it doesn't allow you to edit PDF files, it will allow you to view them and is considered the standard software to do so.
Adobe Acrobat Pro
Adobe Acrobat Pro is the paid version of Adobe Reader. This software provides extensive tools to edit, create, and manage PDF files.
If you are using a recent version of Microsoft Office on a Mac or PC, you can create a PDF file with most applications just by saving the document you're working on. For instance, if you are using Word, you can save the file as a .pdf file. Google Docs offers a similar functionality via Save.
From the Application, Choose "Save As"
(This option can often be found under the File tab)
Choose the file extension available to specifically create a .pdf file
