Why page numbers matter in PDFs
For any document that will be read by multiple people or referred to in discussion, page numbers are essential. 'See the clause on page 12' is much more useful than 'scroll down a bit, it's after the table'.
Page numbers also make printed PDFs professional. A stapled report without page numbers is difficult to reassemble if the pages get out of order.
When you merge multiple PDFs into one document, the combined file may have no numbers or duplicate numbers from the source documents. Adding page numbers after merging ensures consistent sequential numbering across the whole document.
How to add page numbers on Irreva
Open the Add Page Numbers tool and upload your PDF. Choose where the numbers should appear — bottom center is the most common position, but you can also place them at the top or in corners.
Set the font size (12pt is a sensible default for A4 or Letter documents) and choose whether to include a prefix like 'Page' before the number, or just the number itself. You can also set the starting number if the document is part of a larger work and should start at, say, 15 instead of 1.
Click Apply and download the numbered PDF. The numbers are added as a text overlay on each page using pdf-lib in your browser.
- Position: bottom center, bottom left, bottom right, top center, top left, top right
- Font size: typically 10–14pt for body documents
- Start number: useful when this PDF is a chapter within a larger work
- Prefix/suffix: e.g., 'Page 1 of N' or just '1'
Tips for clean page numbering
If your document has a cover page or table of contents that shouldn't be numbered, you can either skip those pages and start numbering from a specific page, or handle them separately by splitting the document, numbering only the pages you want, then merging it back.
For formal reports and academic documents, Roman numerals (i, ii, iii) are traditional for front matter and Arabic numbers (1, 2, 3) for the main body. This requires treating the document as two sections.
Test the result by opening the downloaded PDF and checking a few pages — especially the first, last, and any pages with headers or footers that might overlap with the page number.
