Reports, contracts, and manuals all read better with page numbers — they make references clear and keep printed stacks in order. If your PDF doesn't have them, you can stamp them onto every page in your browser, with full control over where and how they appear.
Why add page numbers?
- Easy references: "See page 12" only works if pages are numbered
- Print order: Keep a printed document in sequence
- Professional polish: Numbered pages look finished
- Legal and academic norms: Many submissions require them
How it works
The Add Page Numbers tool uses pdf-lib to draw a small text label on each page. You choose the position, format, starting number, font size, and margin, and it stamps every page — all in your browser, with nothing uploaded.
Position, format, and start number
Six positions — bottom or top, aligned left, center, or right.
Four formats:
| Format | Looks like |
|---|---|
| Number only | 1 |
| With total | 1 / 10 |
| With label | Page 1 |
| Full | Page 1 of 10 |
Starting number — begin at any value. Set it to 0 or skip ahead when the first page is an unnumbered cover.
Step-by-step
- Open the Add Page Numbers tool
- Drag and drop your PDF
- Choose position, format, starting number, font size, and margin
- Click Add page numbers & download
Tips
- Bottom-center is the most common, neutral choice
- Use a wider margin if your content runs close to the page edge
- Choose "Page 1 of 10" for formal documents where readers want to know the total length
Frequently asked questions
Is my PDF uploaded? No. Page numbers are stamped in your browser; your file never leaves your device.
Can I start from a specific number? Yes — set the "Start at" value, useful when a cover page shouldn't count as page 1.
Will it overwrite existing numbers? It adds a new label at your chosen position; it doesn't detect or replace numbers already printed in the page content.
Is it free? Yes — no account, no watermark, no limits.
