What is a PDF?

PDF is an acronym for Portable Document Format. Adobe® Portable Document Format (PDF) is a nearly-universal standard for electronic document distribution worldwide. Adobe PDF preserves fonts, formatting, graphics, and color of any source document, regardless of the application and platform used to create it. Adobe PDF files are compact and can be shared, viewed, navigated, and printed exactly as intended by anyone with free Adobe Acrobat® Reader® software or with a browser that has a PDF viewer. Most modern web browsers have a PDF viewer that launches automatically when a PDF needs to be rendered. Learn more about creating at editing PDF files in this document PDF Format: Some Basics.

How can I edit a file that is in PDF format?

Not all PDF files are editable – your ability to edit a PDF file depends on how the file was created. Here are a few things to try:

Use Microsoft Word. Open a copy of Microsoft Word (newer versions can edit some PDF files). From within Word, try to open the PDF file you want to edit. If Word begins to convert the file, you will likely be able to edit it. Note that formatting may not convert with 100% accuracy. If the document converts as large images, your ability to edit will be limited.
Google Drive. Upload the PDF in Google Drive. View the document in Drive and select Open With..." Google Docs. Check the resulting document to see if it is editable. If the document has editable text, you can edit it; if it consists of large images rather than text, you will not be able to edit it.
Use Scannx scanners in the library. As a last resort, you can try scanning a printout using the OCR (optical character recognition) feature. The resulting file may permit editing, but formatting of complex documents may not render nicely.

I can't print a PDF. Why?

Some PDF files are designed to prevent printing (the author elected to enable printing protection). Sometimes problems with the PDF prevent printing using normal methods, or documents only partially print. Try these steps:

Open the File Menu
Select “Print”
The Printing window will appear
Click “Advanced”
Put a check in the box next to “Print as Image”
Click OK to close the “Advanced” window
Click OK to print

What is the difference between Acrobat Reader DC and Acrobat Pro DC?

Note: Acrobat Pro has been replaced by Acrobat Pro DC.

DC stands for “Document Cloud” and is a set of applications and services focused on documents, whereas “Creative Cloud” is focused on visual design content creation.

The main difference between Acrobat Reader DC and Acrobat Pro DC is in the functions you can perform.

Acrobat Pro DC enables you to create and modify PDF documents and control what people can do with them, whereas Acrobat Reader DC only allows you to view and print PDF documents.
Acrobat Pro DC lets you review and markup a PDF document and insert comments, while Acrobat Reader DC can only view markup and comments others have made.
Acrobat Pro DC can create forms documents, so that others can fill out—but not change—the form; Acrobat Reader DC only allows you to fill out a form that was previously created.
Acrobat Pro DC also makes it possible to specify restrictions on a document, such as encryption and password protection. With Pro you can limit the ability to copy or print the document.
Acrobat Reader DC is free, Acrobat Pro DC is not.
Acrobat Pro DC is available for use on the iMacs in the Digital Media Studio and the Wilbur Powerhouse as part of their Creative Cloud deployment.

Do I need Acrobat Pro DC?

You do not need Acrobat Pro DC to view or print PDF files, or to create simple PDF documents. Microsoft Office applications can be used to edit, save or export the documents as PDF. Free applications such as PDF995, and web applications such as smallPDF.com, offer creation and conversion of PDF documents. PDF995 displays a popup ad during the creation/conversion process.

Adobe Acrobat Pro DC can be used to do the following:

Directly edit any PDF file
Restrict the ability to print or copy
Create or edit fill-in forms
Use redaction tools (Redaction is the process of permanently removing visible text and graphics from a document. You use the Redact tools to remove content.)

Acrobat Pro DC is available as part of a Creative Cloud Named User License subscription. This is the best way for your department to keep your business essential software current and up-to-date with the latest versions for improved security. The licenses can be reassigned at any time to any Lehigh account, with no extra charge. However, individuals are required to share or save files in a shared location before their license is reassigned.
