Frequently asked questions
Is this page numbering tool free?
Yes. Adding page numbers to your PDF is completely free, with no sign-up, no account, and no watermark on your file.
Are my files uploaded anywhere?
No. Your PDF is processed locally in your browser using pdf-lib and is never uploaded to any server, so it stays private on your device.
What file formats and sizes are supported?
This tool works with PDF files. Because everything runs in your browser, very large PDFs are limited by your device's available memory.
Where are the page numbers placed?
A page number is added at the bottom-center of every page in the PDF.
Can I choose a different position or starting number?
The tool places a number at the bottom-center of every page automatically; custom positions and start numbers are not part of this version.
Do I need to install anything?
No. It runs entirely in your web browser, so there is nothing to download or install.
