Frequently asked questions
Will this change my original PDF?
No. The tool creates a new copy of your PDF with the numbers stamped on each page. Your original file on your device stays untouched.
Can I start numbering from a page other than 1?
This tool numbers pages sequentially from 1. If you need a custom start number, that option is planned for a future update.
Is my PDF uploaded anywhere?
No — numbering happens entirely in your browser with the pdf-lib library, so your PDF never leaves this page.
