What is it?
Add Page Numbers to PDF puts numbers on every page of a PDF: in any corner or the centre, top or bottom, in styles like “1”, “Page 1” or “Page 1 of 9”. You can start from any number and leave front pages, such as a cover, unnumbered.
Who is it for?
Students submitting theses and project reports, lawyers and clerks preparing court files, offices assembling tenders, and anyone printing a booklet or a long merged PDF that needs page references.
How to use it
- Choose a PDF.
- Pick the Position (including Outside corner (books)), the Style, First number and how many pages to Leave unnumbered.
- Set Size, Margin and Colour (Black, Grey or Blue), then tap Add page numbers.
Worked example: a project report
A report with a cover and an index page: set Leave unnumbered to 2, First number to 1, style “Page 1 of N”. The third page becomes Page 1, and N counts only numbered pages.
Books and double-sided printing
Outside corner (books) puts numbers bottom right on right-hand pages and bottom left on left-hand pages, so they’re always on the outer edge when the pages are bound.
The PDF is opened and changed inside your browser; it is never uploaded. Close the page and it is gone.
Errors and how to fix them
- “This PDF is password-protected. Remove the password first”: open it once with Remove PDF Password (you need the password), then use the unlocked copy here.
- “Every page would be skipped: lower “Leave unnumbered””: you asked to skip as many pages as the PDF has.
- Numbers overlap a footer: increase the Margin or move the numbers to the top.
- Numbers wrong after merging: add numbers after you merge, not to each part before.
