🔢 Add Page Numbers to PDF

Adding page numbers to a PDF is simple with our free online tool. Upload your PDF file, customize the number format and position (top, bottom, left, center, or right), choose your starting page and number, then click "Add Page Numbers." The tool processes everything in your browser for complete privacy and downloads the numbered PDF instantly.

Our tool offers multiple professional page number formats: simple numbers (1, 2, 3...), page format (Page 1), page with total (Page 1 of 10), and fraction format (1 of 10). You can customize font size from 8px to 20px, choose any color, and position numbers in headers or footers at any alignment.

Yes! You can start page numbering from any page in your document and choose what number to begin with. For example, you can start numbering from page 3 and begin with number 1, or start from page 1 but begin with number 5. This is perfect for documents with cover pages or when combining multiple PDFs.

Page numbers can be placed in six different positions: top-left, top-center, top-right, bottom-left, bottom-center, or bottom-right. You can also adjust the margin distance from page edges (5-100 pixels) to ensure perfect placement that doesn't interfere with your document content.

No, adding page numbers does not modify or interfere with your original document content. Page numbers are added as overlay text elements in the margins or designated areas. The layout, formatting, images, and all existing content remain exactly as they were in the original PDF.

Password-protected or encrypted PDF files cannot be modified until they are unlocked. You'll need to remove the password protection first using the original password. Once the PDF is unlocked, you can add page numbers normally. For security reasons, our tool cannot access or modify encrypted documents.

There's no strict file size limit as processing happens in your browser, but performance depends on your device's memory. For optimal results, we recommend files under 100MB. Very large files may take longer to process. The tool works with PDFs of any page count and maintains quality regardless of document size.

Yes! Our tool includes a real-time preview feature that shows exactly how your page numbers will appear. As you adjust the format, position, font size, color, and margins, the preview updates instantly so you can see the final result before applying the changes to your PDF.

Our PDF page numbering tool is completely free with no hidden costs, watermarks, or registration requirements. You can add page numbers to unlimited PDFs with full access to all formatting options, positions, and styles. There are no restrictions on document length, file size, or usage frequency.
