How to add page numbers to a PDF

To add page numbers to a PDF, open it in a page-number tool, choose where the numbers should go, such as the bottom centre, and apply them to every page. The tool stamps the right number on each page automatically. It takes seconds and makes long documents far easier to read, print and discuss.

Why page numbers matter

Page numbers seem minor until they are missing. They help when:

• someone says "see page 14" in a meeting or a phone call;
• a printed document is dropped and the pages need putting back in order;
• a reviewer wants to point to a specific clause;
• you merge several files and need one continuous sequence;
• a form, application or legal document asks for numbered pages.

If you add page numbers to a PDF before you send it, the document also looks finished and professional. If you send a long PDF without them, expect people to describe pages as "the one with the table" or "about halfway through", which wastes everyone's time.

How to add page numbers to a PDF on your phone

1. Open the PDF in a page numbers tool.
2. Choose the position: bottom centre is the most common, bottom right also works well.
3. Choose the format, such as "1", "Page 1" or "1 of 20", if the tool offers options.
4. Apply to all pages.
5. Save as a new file.
6. Scroll through and check the numbers do not overlap any text.

If your pages already have numbers from an earlier version, check you are not adding a second set. When you add page numbers to a PDF that will be printed double-sided, a centred position looks the same on left and right pages.

Where to put page numbers

• Bottom centre is the classic position for reports, essays and books.
• Bottom right is easy to see when flicking through printed pages.
• Top right suits some legal and academic documents, and keeps the bottom free for footnotes.

Look at the margins first. If text runs close to the bottom edge, a top position may avoid overlaps.

Page numbers after merging files

When you merge several PDFs, each original file may have its own numbering that starts again at 1. The merged document then has confusing numbers. The fix is simple:

1. Merge the files first. See how to merge PDF files on your phone.
2. Reorder or delete any pages.
3. Add page numbers last, so they run cleanly from the first page to the final page.

If the old numbers clash with the new ones, place the new numbers in a different corner, or crop away the old footer if it is in the margin.

Page numbers with more information

Sometimes a number on its own is not enough. You may want the document title, a date or a "Confidential" label alongside it. For that, use a header or footer, which can carry text in each corner as well as the page number. The headers and footers guide shows the options.

Page numbers and a table of contents

For long PDFs, such as manuals, reports or study notes, page numbers work best together with a table of contents. Readers can see the section they want, then jump to it. In a PDF, bookmarks give you a clickable contents list in the reader's sidebar. See how to add bookmarks and a table of contents to a PDF.

Common problems and fixes

Numbers overlap text. Move them to another position or make them smaller.

Numbering starts on the cover. Many documents do not number the cover. If your tool numbers every page, consider keeping the cover as a separate file and merging it after numbering.

Numbers are hard to see on dark pages. A scanned page with a dark background can hide the number. Try a different position where the page is lighter.

Pages are different sizes. Mixed sizes can make numbers sit in different places. Resizing all pages to one standard size first gives consistent placement.

Adding page numbers with PDF Burrow

PDF Burrow has a Page Numbers tool that adds automatic page numbers to a PDF, and a Header & Footer tool for custom headers and footers with text, page numbers and the date in each corner. Both run on your phone, so the file is not uploaded. For long documents, Bookmarks / TOC builds a table of contents that readers show in their sidebar.

Frequently asked questions

Can I remove page numbers from a PDF?

If the numbers are part of the page content, removing them takes a PDF editor or cropping the margin. Keep an unnumbered copy if you think you might need one.

Will page numbers show when I print the PDF?

Yes. Numbers added to the page are printed like any other text. Check the print settings do not cut off the margins where they sit.

Can I number only some pages?

Many simple tools number every page. A practical workaround is to split the document, number the part you need, and merge the pieces back together.

Do page numbers change the size of the PDF?

Barely. A few characters per page add almost nothing to the file size.
