β Frequently Asked Questions
How much does page numbering increase file size?
Very little. Page numbers are added as text elements via the pdf-lib library. For a 100-page PDF, the size increase is typically under 10KB.
Can I customize font size and color?
Yes. You can choose page number position (bottom center, left, or right), font size (small/medium/large), and starting page number. Advanced options allow font and color customization.
Does my PDF get uploaded to any server?
No. Everything runs locally: Position and Font Size are processed on your device, never sent to a server. Your file never leaves your device, ensuring complete privacy and data security.
Can I start numbering from a specific page?
Yes. Set the starting page number in the options. If the first 2 pages are a cover and table of contents, you can skip them and start numbering from page 3 as page 1.
Will page numbers overlap with existing content?
Page numbers are placed in the bottom margin area to avoid body content. If your PDF already has footers, choose a different position like bottom-left or bottom-right to avoid overlap.
