Renumbering the thumbnail pages

You can use Acrobat’s Page Numbering feature to renumber the pages in the Pages palette to match the page numbers shown on the pages of the document in the Document window. You need to do this, for example, when you’re dealing with a PDF document that contains front matter that uses a different numbering scheme (usually lowercase Roman numerals as in i, ii, iii, and so on) from the body of the text (usually numbered with Arabic numerals as in 1, 2, 3, and so on).
Because Acrobat automatically numbers pages in the Pages palette and in the Page Number area on the status bar of the Document pane in Arabic numerals, starting at page 1, the page numbers displayed in the Pages palette and on the status bar do not match those shown in the document pages themselves when they use different numbering styles. This can make it harder to find your place in the document when doing review and making touchup edits. For that reason, you should renumber the pages in the PDF document so that the page numbers in the document agree with those displayed in the Pages palette and on the status bar.
Keep in mind that renumbering the pages in the Pages palette has absolutely no effect on the page numbers shown on the pages in the Document pane, as these actually represent the page numbers added to header or footer of the document before it was converted to PDF. To renumber the pages of a PDF document, you need to manually edit them in Acrobat or open the source document with the original program, updating the page numbering, and then redistill the file.
To renumber the thumbnails in the Pages palette to match those shown on the pages of the PDF document, take these steps:

1. Select Number Pages on the Options menu at the top of the Pages palette. The Page Numbering dialog box opens, as shown in Figure.
2. Choose how you want to renumber the pages. To renumber all the pages in the document, click the All radio button. To renumber only the pages that you’ve selected in the Pages palette, leave the Selected radio button chosen. To renumber a specific range of pages, select the From radio button and then enter the first page number in the From text box and the last page number in the To text box. To change the numbering style for the specified range, leave the Begin New Section radio button selected. To continue numbering when a range of pages is specified, click the Extend Numbering Used in Preceding Section to Selected Pages radio button.
3. When you’re beginning a new numbering section, select the numbering style on the Style drop-down list, specify any prefix to be used in the number (for example, 2- when you want the numbers to appear as 2-1, 2-2, 2-3, and so on) in the Prefix text box, and enter the beginning number in the Start text box if the section numbering begins at a number higher than 1.
4. Click OK to renumber the pages as specified.
