Align PDF Form Fields to a Grid
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.

Arrange Images in a PDF

Attach Files as Annotations in a PDF
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.

Batch Processing PDF Files
Repetitive tasks involving one or several documents can be automated with the Batch Processing tool.
Security
Certificate security
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.
Forms
Calculate Field Data
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 Auto Build Bookmarks feature can totally automate the creation of bookmarks in your PDFs, and with very little effort greatly enhance the usability of the PDFs you publish.

You can also use it to build bookmarks based on the textual and numerical content of the PDF files by using the text masking and wildcards features.
