Absolutely. At Utilix, data security and user privacy are our highest priorities. When you use our **Add Page Numbers** tool, all file processing, including the reading of your PDF document and the addition of pagination, occurs entirely on your local computer, directly within your web browser. Your sensitive PDF documents are never transmitted to our servers, nor are they stored by us at any point. This client-side operation guarantees that your data remains completely private and secure throughout the entire **PDF pagination** process. You can confidently **number PDF pages** without any concerns about your information being exposed, as it never leaves your device. This is a truly privacy-first **online PDF tool** for document organization.

Yes, the Utilix **Add Page Numbers** tool, along with all other utilities available on our platform, is 100% free to use. There are no hidden costs, subscription fees, or limitations on the number of times you can **paginate PDF** files or the size/page count of your documents. We are dedicated to providing essential, high-quality tools that are accessible to everyone, empowering you to quickly **add page numbering to PDF** documents for various purposes without any financial barriers. Utilize our **free PDF pagination tool** with confidence.

Currently, the Utilix **Add Page Numbers** tool applies a standard font (typically Helvetica), a default size (12pt), and a black color for the page numbers to ensure consistency and readability across all documents. While it provides a clean and professional look, it does not offer advanced customization options for font style, size, or color. The focus of this **PDF page numbering** tool is on quick, simple, and effective pagination. For advanced aesthetic control, you would typically need more sophisticated desktop PDF editing software. We may consider adding more customization features in future updates.

The Utilix **Add Page Numbers** tool is designed to apply consistent pagination across *all pages* of the uploaded PDF document. It does not currently support adding page numbers only to a selection of pages or excluding specific pages (like a title page). The functionality ensures uniform **PDF pagination** throughout the entire file. If you need to paginate only certain sections, a workaround would involve using our “Split PDF” tool to extract the desired pages, add numbers to that smaller PDF, and then potentially use a “Merge PDF” tool to re-combine it with the rest of your document, albeit with potential numbering inconsistencies.

No, our **Add Page Numbers** tool is designed to intelligently place the page numbers in the margins of your document, specifically in the chosen corner or center. It will draw the page numbers on top of the PDF content, but in a way that minimizes interference with existing text or graphics, assuming standard margin sizes. However, if your PDF has content (e.g., footers, logos, text boxes) extending very close to the edges of the page where the numbers are placed, there is a slight possibility of overlap. We strive to place them clearly without obscuring critical information, but it’s always recommended to review the **PDF with page numbers** after download.

While our **PDF pagination tool** has no hard-coded limits on the file size of your PDF document or the number of pages it contains, all processing occurs entirely in your web browser. Therefore, the performance and the maximum data you can effectively handle are directly linked to your computer’s available resources, particularly its RAM and CPU. Adding page numbers to very large PDF documents (e.g., hundreds of megabytes or files with thousands of pages) might consume significant system resources, potentially causing your browser to slow down, freeze, or even crash. For an optimal experience when you **number PDF pages**, we recommend using a modern web browser on a device with ample memory and processing capabilities.

**Adding page numbers to a PDF** offers significant benefits for document organization and usability. Primarily, it enhances navigation, making it much easier for readers to find specific information or refer to certain sections, especially in long documents. For printing, **PDF page numbering** ensures that if pages get separated, they can be easily reordered. It also lends a professional and polished appearance to reports, academic papers, manuals, and other documents. In short, pagination is a fundamental element of document management, improving both the functionality and presentation of your PDF files, making our **paginate PDF** tool invaluable.
