Add page numbers to a PDF for free
This free tool adds page numbers to a PDF directly inside your browser. Choose where the numbers appear — any corner or the center of the top or bottom — and pick a format such as a plain number, 1 / N with the total, or Page 1 of N. You can set which number to start from, the font size, and the margin from the edge. Then download the numbered PDF.
Because everything runs locally with JavaScript, your document is never uploaded to a server and stays private. Page numbers make reports, contracts, and study material easier to reference and print. It works on desktop and mobile and runs offline once loaded.
How to add page numbers
Add your PDF, choose a position and format, set the start number and size if needed, and press Add page numbers to download the result.
Frequently asked questions
Is my PDF uploaded to number it?
No. Page numbers are added entirely in your browser. Your file never leaves your device or gets stored.
Can I start numbering from a number other than 1?
Yes. Use the Start at field to begin from any number, which is handy when a document continues from another file.
Where can the numbers go?
In any of the six positions: top or bottom, and left, center, or right.
Will it cover my content?
The numbers sit in the margin you choose. Increase the margin or reduce the size if they overlap your text.
Does it work on my phone?
Yes. It is fully responsive and works in mobile browsers on iPhone and Android.
