Drop a PDF to stamp page numbers onto it — numbering is applied in your browser and the file never leaves your device.
How it works
- Six number formats including Roman numerals (common for front matter) and "Page X of Y" totals.
- Skip first N pages leaves cover pages unnumbered — the count still starts from your chosen number on the first numbered page.
- Choose from three standard PDF fonts, any color, size, and margin from the page edge.
- A short ad plays before your download starts — it helps keep this tool free. Processing itself happens instantly; the ad is just a brief pause before the file downloads.
- All processing happens locally in your browser using pdf-lib — your files are never uploaded anywhere.
Decide what your page numbers mean
Page numbering becomes much easier when you decide what the number represents before editing the PDF.
For a standalone document, starting at page 1 is usually the simplest option. For a section that belongs to a larger report, you may need to continue numbering from an earlier file. For front matter, Roman numerals may make more sense than using the same numbering style throughout the document.
Position matters as well. A number can technically be correct while being visually difficult to read because it overlaps an existing footer, table, signature, or edge of the page. Check pages with unusual layouts instead of looking only at the first page.
Mixed page sizes and orientations deserve extra attention. A PDF containing portrait pages, landscape pages and scanned pages may look fine in a basic editor while exposing placement problems after numbering.
Keep the original PDF and produce a numbered copy. This gives you a clean source if the numbering needs to be changed later.
After export, check references in the document. If the text says "see page 12", confirm that page 12 still corresponds to the intended content.
Frequently asked questions
Can I start numbering at a specific number?
Yes. Set the starting number before generating the PDF. This is useful when the file is one section of a longer document.
Can I use Roman numerals?
Yes. The tool supports numbering formats including Roman numerals, which can be useful for front matter.
Where can the page number appear?
You can choose the page-number position and adjust the font size. Check the first and last pages after export, especially if the PDF already contains footer content.
Are my PDFs uploaded?
The page-numbering operation is performed locally in your browser. The PDF is not sent to an AllDays processing server by the core page-numbering workflow.
Adding a visible page sequence
This tool stamps a page number onto each page, usually in a header or footer position. The numbers it adds are what a reader sees printed on the page — a running 1, 2, 3 through the document — which makes a printed or shared PDF easier to navigate and reference.
Displayed numbers versus internal order
There's a subtle distinction: the number printed on a page is separate from the PDF's internal page order. A document might start its visible numbering at a different point (say, after a cover), even though internally the cover is still the first page. The stamped number is for the human reader.
Why numbering helps
Once pages are numbered, you can refer to "page 7" in an email or a discussion and everyone is looking at the same place. For long reports, agreements, or handouts, that shared reference is the whole point.
Printed page numbers and PDF page positions are not always the same
A book can have unnumbered covers, Roman-numeral front matter and Arabic-numbered chapters. The physical position of a PDF page and the number printed on that page can therefore differ.
Why numbering became navigation
Page numbers originated as a way to reference locations in fixed documents. In digital PDFs they remain useful because a fixed page sequence survives printing, sharing and offline reading.
