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.

Automatic page number links
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 .

Compare PDF Files
Reporting all the modifications made to a document is a difficult task if changes weren’t tracked during the editing process. Comparing the new document with its original version is the easiest way to pinpoint every single change that was made. To compare two versions of the same document, convert them to PDF in Nitro Pro and use the Compare tool to identify any differences in text, images, and even annotations.

Create Bookmarks Automatically
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. Use it to auto-generate bookmarks based on the font styles (headings, chapters, etc.) and the layout used in your PDFs. 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.

Create a Bookmark in a PDF
You can create bookmarks by selecting text on a page and making it a bookmark, or by adding an untitled bookmark and then setting and naming it in the Bookmarks pane.
Forms
Create a Check Box Field in a PDF
In almost all cases you should use unique field names when creating form fields. If you use the same name for a field, like a text field, data typed in the field box is replicated for all fields with the same name. The exception to the rule is when creating check box and radio button fields. If you want one check box or radio button in a group to be unchecked as another check box or radio button is checked, you use the same field name. Both these field types have an option for adding an export value. When you create fields with the same name, you use different export values to distinguish one choice from another.
