Nitro Pro includes tools so you can add new text to a PDF document, or make last-minute corrections and updates, without the need to re-open the source files in the authoring program.

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.

You can view annotation attachments in the Commenting pane and the Attachments pane.

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.
