Add Page X of Y numbers to the bottom of every page in a PDF.
How to Use PDF Page Numbering
Upload your PDF.
Click Add Page Numbers.
Check the preview, then click Download Result.
Where the numbers go
Every page gets Page X of Y at the bottom centre, about 7 mm above the bottom edge, in small grey text (9 point). The total count updates automatically, so a 12-page document reads Page 1 of 12 up to Page 12 of 12. Nothing else on the page is changed or re-compressed.
There are no layout options yet, so you can't choose a different corner, a starting number or a format like 1/12. If your pages already have something printed in the bottom margin, check the preview for overlap before downloading.
Number after you merge
If you're combining several files, merge them first with the PDF Merger and number the finished document, so the count runs from start to end without restarting.
Key Features & Practical Use Cases
Numbering a merged PDF so people can say which page they mean.
Adding page numbers to a report or assignment before submitting it.
Making printed handouts easy to put back in order.
Frequently Asked Questions
Can I start numbering from a page other than 1?
Not at the moment. Every page is numbered, starting from 1.
Can I put the numbers at the top or in a corner?
No, they're always at the bottom centre.
Does it work on scanned PDFs?
Yes. The number is drawn on top of the page, whatever it contains.
Is my PDF uploaded?
No. The numbers are added in your browser with pdf-lib.
