Frequently asked questions

Where are page numbers added?

Page numbers can be positioned at the bottom center, bottom left, bottom right, top center, top left, or top right of each page.

Can I customize the font and size?

Font size and style options are available. You can choose a size that fits your document style.

Can I start numbering from a specific number?

Yes. If your document starts at page 5 in a larger document, you can set the starting number accordingly.

Does adding page numbers change the PDF layout?

Page numbers are added as an overlay on top of the existing content. They appear over the content area rather than adding a new margin. If your document already has narrow margins, ensure the number position does not overlap important content.

Can I add page numbers to a scanned PDF?

Yes. Page numbers are added as a text overlay on each page image. The underlying scanned content is unchanged.

Does this tool require an internet connection?

No. Everything runs locally in your browser.
