Frequently Asked Questions
Is my PDF uploaded to a server?
No. Page numbers are stamped with pdf-lib entirely in your browser. Your file never leaves your device.
Where can the numbers go?
Any of six positions: bottom or top, aligned left, center, or right. You also control the margin distance from the edge.
What number formats are available?
Plain (“1”), with total (“1 / 10”), with the word Page (“Page 1”), or both (“Page 1 of 10”). You can also set the starting number.
Can I start numbering from a specific number?
Yes. Set the “Start at” value — useful when the first page is a cover you want to skip counting from.
Is it free?
Yes — completely free, no account, no watermark, no limits.
