How do I add page numbers to a PDF?
Drop the PDF into the box above, pick a position, a format, a start number and a size, and watch the preview. When the number sits where you want it, click “Add page numbers” and download the result. You don’t need Acrobat or a paid editor, and the whole thing takes less time than opening a desktop app.
Each page gets a small line of text in the spot you chose. Everything else stays exactly as it was, so the existing text, images and layout are untouched, and the numbered file is saved as a new copy next to your original. The preview helps you avoid clashes with an existing footer or a dark scanned edge.
Tip: Merge your files into one PDF before numbering. That way the sequence runs through the whole document instead of restarting for each part.
How do I add “Page X of Y” to a PDF?
Choose the “1 of N” format. Each page then shows its own number together with the total, such as “3 of 12”, so a reader can tell at a glance that nothing is missing. That is why offices often ask for it on contracts, long forms and anything that gets printed and stapled.
- Bottom center or bottom right is the usual choice for reports. A corner suits double-sided printing, where the number sits near the outer edge.
- Use “1 of N” for forms and contracts. The total makes a missing page obvious.
- Use the plain “1” for books and theses, where the table of contents already tells readers how long the document is.
- Keep the size modest. Roughly the size of your body text works well. Very large numbers look like a stamp.
- Watch the footer. If the page already has one, move the number to another position so they don’t overlap.
Can I start page numbering from page 2 or 3?
The tool always numbers every page in the file, but you choose which number the first page gets. That covers two common cases. If this PDF is chapter two of a longer report, start at the right number so the sequence continues. If the cover and contents pages must stay unnumbered, take them out first with Split PDF, number the remaining pages starting at the right value, then put everything back together with Merge PDF.
This takes a minute longer than a single button, but it gives you clean front pages and numbering that matches what the table of contents says.
Is it safe to add page numbers to a PDF online?
Yes. You reach the tool online, yet the numbering happens on your own computer or phone. Your browser opens the PDF, writes the numbers onto each page and hands back the new file. The document is never sent to a server, which is reassuring for a thesis before submission, a signed contract or an internal report.
To see it for yourself, open your browser’s network tab and number a file. No file data leaves your device, because the numbers are written right in your browser. Nothing to install, so it works the same on a phone or a laptop.
