To continue using Nitro Pro after the trial period has expired, it is necessary to purchase a license that must be activated on your computer. Activation ensures that you have bought a genuine Nitro product by linking the software license to the computer on which it is installed.

The Insert Image tool lets you add images to your PDF files so you don’t need to go back and edit the original source file.

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.

The image arranging tools let you move images in front and behind other objects on the page, flip or mirror, and rotate them.

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.

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

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.

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.

The Comments Pane gives you a centralized place to see and organize all of your annotations. It lists each comment, its type, reviewer name, date added, and the text included in any pop-up notes and text boxes.
