Is adding page numbers to a PDF free?
Yes. This tool adds page numbers to a PDF free, with no signup or watermark. It runs in your browser, so there is nothing to install.
Does this upload my PDF to a server?
No. The page-number stamping runs locally in your browser, so the source PDF stays on your device the whole time and is never uploaded.
Can I start numbering from a custom number?
Yes. You can set the starting number so the first numbered page begins at any positive value, which is useful when a cover or contents page comes first.
Can I place the numbers in the top or bottom corners?
Yes. The position options cover common top and bottom placements, and you can adjust the margin so the numbers sit cleanly away from the page edge.
Does it work on mobile?
Yes. The tool runs in any modern mobile or desktop browser, so you can number a PDF on a phone or tablet without installing an app.
Should the cover page be numbered?
Usually not, and forgetting that is the most common mistake. Start the numbering from the first page of content rather than from the first page of the file.
What if the PDF already has page numbers printed on it?
This adds new ones; it does not replace what is already there. You will end up with two sets, so check before you stamp.
Where should the page numbers go?
The outer corner for a document that will be printed and bound, the centre for one read on screen. Keep them clear of tables and footnotes, where they read as mistakes.
Should I number before or after merging?
After. Numbering first and then reordering the pages produces a document whose numbers are wrong in a way that looks deliberate.
Can I start numbering from a page other than the first?
Yes, and you usually should: covers, title pages and prefaces are normally excluded from the count.
