The Complete Guide to Adding Page Numbers to PDF Files Privately
Adding page numbers to multi-page contracts, manuscripts, academic theses, legal exhibits, and business reports ensures clear document pagination and professional formatting. The MyPDF Add Page Numbers tool lets you customize page numbering position, starting page indices, margin offsets, and font styles—100% inside your web browser.
Customizing Page Numbering Formats & Facing Page Modes
- Single Page & Facing Page Modes: Place numbers consistently in headers or footers, or alternate left/right positions for book and magazine binding.
- Flexible Starting Index & Ranges: Choose custom starting page numbers (e.g. starting numbering from Page 3 to skip cover pages and tables of contents).
- Vector Text Layer Injection: Numbers are rendered directly into the PDF vector layer using PDF-Lib, maintaining 100% vector crispness without re-compressing underlying document pages.
Why In-Browser Page Numbering Protects Privacy
Uploading confidential corporate filings or draft manuscripts to online PDF tools risks data harvesting. MyPDF processes all page layout streams locally inside your browser's client memory. Your files and page contents are never sent to external servers.

Frequently Asked Questions About PDF Watermarks
Is it safe to add page numbers online?
Yes, with MyPDF it is completely safe. Unlike other online tools, your files are processed entirely in your browser using JavaScript. Nothing is uploaded to any server. Your documents stay on your device at all times.
Can I use an image as a watermark?
Yes. You can toggle between Text and Image modes. In Image mode, you can upload a JPG or PNG file (like a company logo) to stamp onto your document.
Will adding page numbers reduce PDF quality?
No. MyPDF stamps the vector text or image directly onto the existing document layer without re-rendering or compressing the original pages, preserving 100% quality.
Does this work on mobile devices?
Yes. The split tool works on any device with a modern browser — iPhones, Android phones, iPads, tablets, and desktop computers. No app installation required.
Is there a file size or page limit?
No artificial limits. Since processing happens in your browser, the only limitation is your device's available memory. PDFs with hundreds of pages work without issues on most devices.
