About the Add Page Numbers to PDF Engine
Numbering a PDF by hand or re-exporting from a source document just to add "Page X of Y" wastes time. iCreatePDF stamps sequential page numbers onto an existing PDF directly in your browser, so contracts, theses, reports, and manuals get consistent pagination without a trip through a desktop editor or a third-party upload.
Zero-Server Privacy Architecture
Unlike conventional web utilities that transmit your files to cloud processing clusters, iCreatePDF executes add page numbers to pdf completely client-side. WebAssembly modules and local JavaScript engines handle all parsing, layout calculation, rendering, and file encoding inside your browser sandboxed memory buffer. Your files never cross network boundaries.

Frequently Asked Questions
Q: Can I start numbering from a page other than 1?
Yes. Set any starting number, which is useful when a numbered PDF continues from a previous volume or appendix.
Q: Will page numbers overwrite existing content?
No, the stamp is placed in the margin position you choose so it does not overlap your existing text or images.
Q: Does this tool support "Page X of Y" formatting?
Yes, you can choose a simple counter or the "Page X of Y" label format used in most legal and academic documents.
Q: Is my document uploaded to a server?
No. Numbering happens entirely client-side using WebAssembly, so your file never leaves your browser.
