Add professional page numbers to any PDF document. Choose where to place them - top or bottom of the page, aligned left, center, or right. Customize the font size, color, and starting page number. Skip numbering on the first page if it's a cover. Preview your numbered pages before downloading. Perfect for reports, manuscripts, legal documents, or any multi-page PDF that needs page references. Page numbers are added as a text overlay without altering the original content. All formatting and content of your PDF is preserved. Processing happens entirely in your browser.

How it works
PDFWhisk uses PDF-lib to add text elements to each page of your PDF. Page numbers are drawn as new text overlays at your chosen position and style. The original page content is untouched - numbers are simply layered on top. No quality loss occurs.
Frequently asked questions
Where can I place the page numbers?
Choose from 6 positions: top-left, top-center, top-right, bottom-left, bottom-center, or bottom-right. Bottom-center is the most common choice.
Can I skip the first page?
Yes. Toggle 'Skip first page' to omit the page number from the first page (useful for cover pages). Numbering starts from page 2.
Can I change the starting number?
Yes. Set any starting number. For example, start at page 3 if your first two pages are a cover and table of contents from another document.
What fonts are available?
Page numbers use the standard Helvetica font, which is clean and professional. You can adjust the size from 8pt to 24pt and choose any color.
Will this work on scanned PDFs?
Yes. Page numbers are overlaid on top of any page content, whether it's scanned images or digital text.
