How to use Add page numbers
- Select or drop your PDF.
- Choose position (e.g. bottom center), format, starting number and font size. Tick “Skip first page” for a cover.
- Click “Add page numbers” and download.
Formats for every document
Use simple 1, 2, 3 for reports and theses, 1 / N for handouts, or Page 1 of N (in your language) for contracts so readers can see nothing is missing. Set a different starting number when your PDF continues from another document.
Clean placement
Numbers are placed inside the page margin and drawn as a crisp high-resolution image, so they print sharply. Combine with Merge PDF to number a set of documents continuously.
🔒 Your files never leave your device
bopdf processes your documents locally with JavaScript (pdf-lib and Mozilla pdf.js) inside your browser tab. Your PDF is never uploaded, stored or seen by us — you can even disconnect from the internet after the page loads and the tool keeps working. When you close the tab, everything is gone.
Frequently asked questions
Can I skip the cover page?
Yes — tick “Skip first page”. Numbering then starts on page two.
Can I start from a number other than 1?
Yes — set any value in “Start at”.
Will numbers overlap my content?
They are placed about 8 mm from the edge. If your pages have very narrow margins, try a smaller font size or a corner position.
Is my PDF uploaded?
No. Numbers are added in your browser.
Are my files uploaded to a server?
No. Everything happens in your browser on your own device. Files are never sent over the internet, which makes bopdf suitable for confidential documents.
Is there a file size limit?
There is no fixed limit, but very large files (hundreds of MB) depend on your device memory. On phones, files up to about 100 MB usually work well.
