Using PDF documents

In addition to viewing PDF files, you can modify and annotate them in a variety of ways.

Viewing PDF files
When reading a PDF file, you can quickly find what you want by searching it, using its table of contents, or adding bookmarks. You can also make it easier to read by zooming in or out.
Modifying PDF files
You can move pages around and delete them or rotate them as needed. Add effects that shrink a PDF document or change its colors. And even fill out a PDF form.
Annotating PDF files
You can add your own comments to a PDF file, mark up important sections, and add links to websites or other pages in the document.
