PDF Page Numbering — Frequently Asked Questions
Everything you need to know about using PDF Page Numbering.
Is my PDF uploaded?
No. The entire PDF manipulation happens in your browser using pdf-lib. Your document never leaves your device.
Will it work on password-protected PDFs?
No — you need to unlock the PDF first. Use our PDF Unlocker tool, then add page numbers.
Can I number only specific pages?
Currently this tool numbers all pages. To skip pages, use our PDF Splitter first to remove them, number the rest, then merge if needed.
What if my PDF already has page numbers?
The tool adds new numbers on top — you may end up with two sets. Either remove the existing layer first (with our PDF Editor) or just keep the original.
Can I customize the font?
Currently the tool uses a clean built-in font (Helvetica) for maximum compatibility. Font family selection is on the roadmap.
