Add Page Numbers stamps sequential page numbers onto every page of your PDF. Choose from six positions (top or bottom, left/center/right), set a custom start number, add a prefix or suffix (e.g. "Page 1" or "1 / 10"), and adjust the font size. It's essential for reports, legal documents, theses, or any multi-page file that needs clear navigation.
Upload your PDF and configure the numbering options: pick a position from the 3×2 grid, set your start number, choose font size, and optionally add a prefix or suffix. Toggle "Show total pages" to display the format "1 / 10". A live preview shows the exact number format before you apply it. Click "Add Page Numbers & Download" and the numbered PDF is ready instantly.
