When a PDF file is created for this purpose, the creator of the file can make the process easier by adding predefined text boxes, check boxes, graphics, links to instructions, just about anything that will make the process of completing the form an easier one. One of the most common uses for a PDF file is as a form intended for an individual to fill out. Preview supports more than just viewing you can also mark up a PDF file in order to add additional information. In other words, that PDF file you’re viewing on a Mac will look the same when viewed on a PC, or for that matter, any device that supports PDFs. PDF (Portable Document Format) is a file format intended to ensure that documents can be exchanged reliably, independent of the type of software or hardware being used to view, print, or edit them. In this Rocket Yard guide, we’re going to explore the Preview app’s ability to fill out PDF forms and mark up files, even files that weren’t designed to be completed electronically. It includes a number of features and services that can be used for editing PDFs, working with images, even creating electronic signatures to use to sign important documents. Preview, the free PDF viewing app included with the Mac, can do a lot more than view images or open PDF files to view.
