FAQ

Is my PDF uploaded to a server?
No. Everything happens locally in your browser using pdf-lib — your file is never sent anywhere.
Can I start numbering from a page other than 1?
Yes. Set any starting number and every page will be numbered sequentially from that value.
Will the page numbers include a watermark or branding?
No. You get a plain page number in your chosen position and format — nothing else is added to your document.
