How to Add Page Numbers to a PDF

Why add page numbers

Numbers give a document structure and make it easy to reference. Without them, a reader cannot tell if a page is missing or point to a spot in the file. Common reasons to add page numbers include:

• A contract where clauses are cited by page
• A report or manual that needs a clear reading order
• A printed handout where pages could get shuffled
• A legal or court filing that requires numbered pages

Add page numbers in your browser, step by step

Use the free tool at /tools/add-page-numbers. It works free in your browser with no signup, and your files stay private on your own device.

1. Open /tools/add-page-numbers in any modern browser.
2. Add the PDF you want to number by dragging it in or picking it from your files.
3. Choose where the number goes, such as the bottom center, bottom right or top of each page.
4. Pick the starting number if you do not want to begin at one.
5. Preview a page to check the number does not cover any text.
6. Build the file, download it, and confirm the numbers run in order.

Choose a position that does not cover text

The best spot for a page number is a margin with empty space, usually the bottom center or bottom right. Before you build the file, look at a page that has a footer or a table near the edge, because that is where a number is most likely to land on top of existing content. If your pages already have a footer, place the number where it will not overlap.

Set the starting number

You do not always want to start at page one. If your PDF is a chapter that follows a cover and a table of contents, you may want the first numbered page to be three or four. Many tools let you set the starting number so the printed numbers match the real position in a larger document. Decide this before you build the file so you do not have to redo it.

Tips for a clean result

• Keep the number style simple, since a plain number is easier to read than a long label.
• Preview both an early page and a late page to confirm the position works throughout.
• Keep the original file until you have confirmed the numbered version looks right.
• If pages are different sizes, check that the number sits correctly on each one.

Add page numbers on a phone or tablet

The tool works in a mobile browser the same way it does on a computer, because everything runs on your own device. On a phone, open /tools/add-page-numbers, add the PDF, choose the position, and build the numbered file. This is useful when you need to send a numbered copy of a document while you are away from your desk. Very large files can use a lot of memory on an older phone, so if the browser slows down, try it on a computer.

Number pages in the right order

Page numbers follow the order of the pages in the file, so fix the order before you number. If some pages are out of place, reorder them first, and if any pages should be removed, delete them with /tools/delete-pages-from-pdf before adding numbers. That way the printed numbers match the final document. If you add or remove pages after numbering, the numbers will no longer line up and you will need to run the tool again.

What adding numbers does not change

Adding page numbers stamps a number onto each page. It does not change the words already on the page, and it does not fix a page that is out of order or upside down. If a page is rotated, fix that first with /tools/rotate-pdf so the number appears in the right corner. If a file is password protected, remove the password first so the tool can read and stamp every page.

Is it private and free

Yes. The page numbers tool processes your file locally in the browser. Nothing is sent to a server, so sensitive documents and personal records never leave your computer. It is free to use, requires no account, and adds no watermark to the result. Fillable is a product of Four Cents. If you have a question, you can reach the team at info@fourcents.ca.
