Frequently asked questions

Can I start numbering from something other than 1?

Yes — set the "Start Numbering At" field to any number, useful when continuing numbering from another document.

Can I skip numbering the first page (like a cover page)?

This version numbers every page in the document. To skip a cover page, split it into a separate file first, then merge after numbering.

Is my file uploaded anywhere?

No. Page numbers are added entirely in your browser using pdf-lib.
