Under Include non-printable information, put a tick the Create bookmarks using box if you wish to create a set of bookmarks that users can click in the PDF document. Under Publish what, click Document showing markup to include tracked changes in the PDF file otherwise, make sure Document is selected. Under Page range, choose whether to convert the entire Word doc to PDF, current selection or certain pages. This will open the Options… dialog where you can set up the page range and configure some other settings: button in the right part of the Save As window, as shown in the screenshot above. If you want additional options, especially if you wish to avoid exporting information you don't want to share, click the Options. If you are exporting a large file with many images, choosing Standard may increase the file size significantly. If the converted Word doc is essentially text, the difference will be almost unnoticeable.

Most web browsers, like both Chrome and Firefox, can open PDFs themselves. It's completely fine to use, but I find it to be a somewhat bloated program with lots of features that you may never need or want to use. Adobe created the PDF standard and its program is certainly the most popular free PDF reader out there. Most people head right to Adobe Acrobat Reader when they need to open a PDF. PDF files always look identical on any device or operating system.

The reason PDF is so widely popular is that it can preserve original document formatting. The Portable Document Format (PDF) is a universal file format that comprises characteristics of both text documents and graphic images which makes it one of the most commonly used file types today.
