PDF (or Portable Document Format) is the most widely used standard for online distribution and exchange of digital documents across both personal and professional environments. Here are some of the many advantages of using PDF documents:

• PDF is now an ISO certified standard, and is no longer solely controlled by Adobe, meaning that all software vendors can openly implement PDF functionality into their applications
• PDF is compatible across all computing platforms like Windows, Mac, and Linux
• If you create or modify a PDF in Nitro Pro, you can be sure that it will appear the same in other PDF viewers as long as they conform to the PDF Specification
• If a PDF document was designed in another PDF authoring application, such as Adobe Acrobat, then it will look the same when you open it in Nitro Pro
