Why add page numbers to PDFs on PDFDocks?
Long PDFs need page numbers—for reference, navigation, and professionalism. Adding them manually is tedious and error-prone. PDFDocks adds page numbers directly in your browser using JavaScript, letting you customize format, position, and which pages get numbered.
Can I customize the page number format?
+
Yes. PDFDocks offers formats like 1, 2, 3 or i, ii, iii, and lets you choose position (top, bottom, corners).
Can I skip numbering specific pages?
+
Yes. You can exclude the first few pages or any ranges you specify.
Will numbering increase file size significantly?
+
Minimally. Page numbers add very little data to the PDF.
Is my PDF private?
+
Completely. All processing happens locally in your browser.
Can I change numbering after adding it?
+
You'd need to process the PDF again. Keep your original if you might need to re-number.
Do I need software?
+
No. PDFDocks handles everything in your browser.
