You can add documents to My Documents from both your local machine as well as the following storage providers:

With Nitro Pro, you can use grids to assist you in precisely lining up links, form fields, and other objects on a page. When turned on, the grid is visible over your PDF pages; however, grid lines will not be printed when you print your document. You can also customize the grid’s display, setting preferences such as default units, line color, spacing, and other options.

Just like attaching a paper file to another with a paperclip, the Attach File annotation tool enables you to attach electronic files to your PDFs files. Annotation attachments appear as a paperclip icon on the PDF page; reviewers can double-click the icon to open the file. You can view annotation attachments in the Commenting pane and the Attachments pane.

The Create Page Links tool lets you automatically turn all numbers on an area of the page into active hyperlinks that will link each number to the corresponding page in the document. It’s ideal for making sections of documents, like the table of contents and index, more intelligent and easier to use. It’s simply a matter of selecting the part of the page or range of pages you want to scan, and then running the tool to turn them into active links .

Repetitive tasks involving one or several documents can be automated with the Batch Processing tool.

Nitro Pro supports field calculations using several methods. The built-in calculation formulas are an easy means for creating simple, and quite restricted, field calculations. You can also use Simplified Field Notation and JavaScripts, although these methods are much more sophisticated and require some programming knowledge. If your calculation needs are limited to summing or averaging data, you can use the built-in formulas without having to worry about programming.

Digital IDs let you encrypt files that can only be opened and used by people who have exchanged certificates. Certificate-based security has many advantages over password-based security: documents can be opened without the need to remember passwords, Digital IDs cannot be shared or copied easily, the one document can contain different security settings for each recipient of a file. For example, you may grant one person editing and printing privileges, while another is limited to just viewing the file.

With Nitro Pro, you can update the color space of each image individually.
