Add numbering to a document that does not have it — merged files, scans, and exports from tools that leave it out. Choose the corner, the starting number and the size.
Numbers are placed in the page’s visible orientation, so a scan that carries a rotation flag still gets its number in the right corner the right way up rather than sideways in the margin.
The rest of the document is untouched: numbering adds a small amount of text and leaves existing content exactly as it was.
How to use it
Add the PDF that needs numbering.
Choose where the numbers sit, and which page the count starts from — useful when a cover should not be page 1.
Press Apply and download the numbered document.

Where it runs
In your browser; nothing uploaded
Not for: Removing numbers a document already has — a stamped number becomes part of the page and cannot be taken off again.
Frequently asked questions
Are my files uploaded to a server?
No. This conversion runs entirely inside your browser using your own device’s processing power. The file never leaves your computer or phone, which is why it also works when your connection drops.
Can I start numbering at something other than 1?
Yes. Set the starting number, which is what you need when a document continues from an earlier volume or has unnumbered front matter.
Can I use Arabic text in the numbering?
The built-in PDF fonts cover Latin characters only, so Arabic text is refused with an explanation rather than silently dropped. Embedded-font support for Arabic stamping is not in this tool yet.
