Frequently asked questions
Yes. Set any starting number — handy when the file is one chapter of a larger document or when the cover page should not be page 1.
Numbers sit in the page margin (about 1 cm from the edge). On pages with unusually tight margins they may overlap — check the preview page after download.
No. Numbering runs entirely in your browser using pdf-lib — the document never leaves your device.
