A header and footer present consistent information in the page margins throughout a PDF. For example, the information could be a date, automatic page numbering, the title of the overall document, or author’s name.
You can vary the headers and footers within a PDF. For example, you can add a header that displays the page number on the right side of odd-numbered pages, and another header that displays the page number on the left side of even-numbered pages. Each of these headers must be added individually.
You can define and save your headers and footers to reuse them later, or you can simply apply a header and footer and forget it. After applying a header and footer, you can edit, replace, or delete it in the PDF. You can also preview headers and footers before applying them and adjust the header and footer margins so that they don’t overlap other page content.

Define and apply headers and footersYou can add one or more sets of headers and footers to a PDF and apply them either globally or selectively to its pages. Each set of headers and footers must be applied in a separate session in the Add Header And Footer dialog box. Headers and footers can include automatically generated information and formatting, such as page numbering and the current date.
If you use the same types of headers and footers frequently, you can save header and footer definitions so that you can quickly apply them to other PDFs.
If you want to add additional headers or footers, simply repeat this procedure.
