Frequently Asked Questions
Can I exclude the cover page from page numbering?
Yes, you can set the starting page offset (e.g., start numbering from page 2 as page 1) to leave cover pages, title sheets, or table of contents unnumbered.
Where can page numbers be placed?
Choose between Top/Bottom Left, Center, or Right, with custom font size, color, and margin padding.
Does adding page numbers modify existing text or page layout?
No, page numbers are placed into the header or footer margins as clean text overlays without reflowing or compressing existing page graphics.
