Frequently asked questions
Where can I place the page numbers?
Bottom centre, bottom left, bottom right, top centre, top left, or top right.
Can I choose what number to start from?
Yes. Set any starting number — useful if this PDF is one chapter in a longer document.
Is the PDF uploaded to your servers?
No. Processing uses pdf-lib entirely in your browser. Your file never leaves your device.
What is the maximum file size?
No enforced limit, but very large PDFs (100MB+) may be slow depending on your device memory.
Will it work on scanned PDFs?
Yes. Page numbers are added as a text overlay on every page, regardless of content type.
