Frequently Asked Questions
How do I add page numbers to a PDF?
Drag and drop your PDF into the tool, choose a number format, set the start value, pick a position, adjust font size and color, then click Add Page Numbers. The PDF is updated in your browser and ready to download.
Is my PDF file uploaded to your servers?
No. The PDF Page Numbers tool runs completely within your web browser. Your file is read locally and never uploaded or transmitted over the internet.
Can I choose the number format and start value?
Yes. Choose from 1, Page 1, Page 1 of N, or 1 / N, and set any start number. The tool automatically counts total pages for formats that include the total.
