About this tool
Add sequential page numbers to any PDF document. Choose where numbers appear (bottom center, bottom left/right, or top positions), set the starting number, and pick the font size. Numbers are drawn using pdf-lib's text drawing API on each page, embedded in the PDF content stream. Ideal for reports, proposals, e-books, and any multi-page document that needs visible page numbering. No upload, no sign-up, no watermark.

Number pages in any PDF
Whether you are preparing a report, finalizing an e-book, or assembling a multi-section document, page numbers help readers navigate. This tool adds sequential numbers to every page using Helvetica font in your chosen position and size.
Why no upload matters
Your document content is private. Toolisk adds page numbers locally in your browser — the file never leaves your device. No server processes your document, no data is collected.
Frequently asked questions
Is this safe? Does it upload my PDF?+
No upload whatsoever. Page numbers are drawn using pdf-lib entirely in your browser. Your PDF never leaves your device.
What is the maximum file size?+
PDFs up to 100 MB are accepted. Files over 30 MB may be slower on mobile due to the per-page text rendering.
Does it work offline?+
After the page has loaded once, yes — pdf-lib is cached and page numbering runs locally.
Will this work on iPhone / iPad?+
Yes, on modern iOS Safari.
Can I start numbering from a specific number?+
Yes — set the starting number. For example, start at 1 for a standalone document or 42 to continue from a previous section.
Where are the numbers placed?+
Choose from bottom center, bottom left/right, or top center/left/right. Numbers are placed in the margin area.
Will existing page numbers be overwritten?+
The new numbers are drawn over the existing page content. If there are existing numbers, they will still be visible underneath. Consider cropping or using a PDF editor to remove them first.
