Open the combined PDF file in Adobe Acrobat.
In the left pane, open the thumbnails panel by clicking the icon that shows page thumbnails.
Right-click on the first page thumbnail where you want to start renumbering.
Select Number Pages... from the context menu.
In the dialog that appears, set the page range you want to renumber (e.g., all pages or a specific range).
Choose the numbering style (e.g., 1, 2, 3 or i, ii, iii) and enter the starting number or prefix as desired.
Click OK to apply the new page labels.
After merging PDFs, renumbering page labels ensures bookmarks and navigation match the new document order.
This runs in the Acrobat app - there is no separate API for this task.
Page Labels change only the numbers you see displayed in Acrobat for each page, which helps the PDF's on-screen numbering match the physical document's numbering. It does not change the content of the page. Bates Numbering, however, is a feature that stamps a unique, sequential number directly onto the content of each page as if it were ink. This is often used for legal documents to create a permanent, visible record. Page labels are for display, Bates numbering is for permanent marking.
This often happens because PDFs have their own internal page numbering system that starts from '1' for the very first page. If your physical document has an introduction with Roman numerals (i, ii) or starts its main content after a cover page, the PDF's default numbering won't match. The 'Page Labels' feature in Acrobat lets you adjust the displayed numbers to align with your document's specific numbering scheme, making it easier to navigate.
If your PDF has mixed-up page numbers like '1, 2, i, ii, 3, 4', Page Labels can fix the display. You would go into the 'Page Labels' settings and define different numbering ranges. For example, you could set pages 1-2 to be 'Arabic 1, 2', then pages 3-4 (which are currently 'i, ii' in your example) to be 'Roman i, ii', and then the next set of pages to be 'Arabic 3, 4'. This makes the displayed numbers logical and easy to follow.
Page Labels are the system Adobe Acrobat uses to display page numbers or names for each page within a PDF. They matter because they help you and others navigate the document correctly, especially when the printed pages have a specific numbering style (like an introduction with Roman numerals and main content with Arabic numbers). Without correct page labels, finding specific pages can be confusing if the PDF's internal numbering doesn't match the physical document's numbering.
