Frequently Asked Questions

Where do page numbers appear?

Page numbers are placed at the bottom center of each page.

Can I start numbering from a number other than 1?

Yes. You can set any starting number.

Does this modify the original file?

No. The tool creates a new PDF. Your original file is never modified.

Are my PDF files uploaded to a server?

No. All processing happens entirely in your browser using WebAssembly. Your files never leave your device — there are no uploads to any server. After the page loads, the tool works even without an internet connection.

Is this tool free to use?

Yes, completely free. There are no hidden charges, no file size limits, no watermarks on output files, and no registration or account required. Use it as much as you need.

Can I add page numbers on a mobile phone or tablet?

Yes. The tool works in any modern browser on mobile, tablet, or desktop. The interface is responsive and works with touch input. No app download needed.

Will the PDF quality change after processing?

No. The tool preserves your original PDF content and quality exactly. Only the changes you requested are applied — text, images, and layout remain unchanged.

Can I add page numbers if the PDF is password-protected or encrypted?

No. Password-protected or encrypted PDFs cannot be processed. You need to remove the protection first (using a tool like Adobe Acrobat or a free online unlocker), then upload the unprotected file.
