How to Add Page Numbers to a PDF

The Page Number tool draws numbers directly onto each page of your PDF. It reads the page dimensions, calculates the anchor point for the position you pick, then stamps text at that spot. All of this runs in your browser, so the file never leaves your device.

Here is the full flow to add page numbers to PDF documents:

  1. Upload a PDF through the dropzone on this page.
  2. Choose a page number format: 1/2/3, 01/02/03, "Page 1/2/3", "1/10", i/ii/iii, I/II/III, a/b/c, or A/B/C.
  3. Pick a position: Bottom Center, Bottom Left, Bottom Right, Top Center, Top Left, or Top Right.
  4. Set the font size between 8 and 36 pixels (the default is 12).
  5. Set a starting number from 1 to 9999 if you do not want to begin at 1.
  6. Optionally list which pages to number, such as "1, 3, 5-7". Leave it blank to number every page.
  7. Click "Add Page Numbers" and download the result.

How PDF Page Numbering Works

When you insert page numbers to PDF files, each number is written as a new text element layered over the existing content. The tool does not rebuild or re-encode your document. It keeps the original pages intact and adds a small text object at the corner or center you selected.

The starting number setting shifts the count. If you set it to 5, the first numbered page shows 5 and each following page counts up from there. This helps when your document is one part of a larger set that already has earlier pages.

The "1/10" format is different from the others. It shows the current page next to the total page count, so readers know how far through the document they are. The tool reads the total page count from the file itself before stamping.

Numbering Formats Compared

Each format changes how the number renders on the page. The table below shows what each style looks like and where it fits.

Format Example Output Best Use
Arabic 1, 2, 3 Standard documents and reports
Padded 01, 02, 03 Files that need aligned two-digit numbers
Prefixed Page 1, Page 2 Contracts and formal paperwork
Fraction 1/10, 2/10 Long documents where total count matters
Roman lowercase i, ii, iii Prefaces and front matter
Roman uppercase I, II, III Chapter or section markers
Alphabetic lowercase a, b, c Appendices and short indexes
Alphabetic uppercase A, B, C Labeled exhibits and attachments

When to Add Page Numbers to a PDF

Pagination in PDF matters most when a document will be printed, signed, or reviewed by more than one person. Numbers give everyone a shared reference point, so a comment about "page 12" points to the same place for everyone.

Common situations where you would insert page no in PDF files include:

If you assembled the file from several sources first, run the merge tool before you paginate so the numbers flow across the whole set.

How LooPDF Differs From Alternatives

Many editors bury pagination inside a header and footer menu, which forces you through several dialogs. This tool keeps the controls on one screen. You choose format, position, size, and range, then apply them in a single step.

Key differences worth noting:

If you need to reorder pages before adding numbers, use the organize tool first. To remove numbers you no longer want, run the PDF editor .

FAQ

It stamps page numbers onto an existing PDF. The tool reads each page's size, works out the anchor point for your chosen position, then writes a number there as a new text element. The original page content stays untouched. You control the format, position, font size, starting number, and which pages get numbered.

Upload your file, then choose a number format and a position such as Bottom Center. Set the font size and, if needed, a starting number. You can also list specific pages to number. Click "Add Page Numbers" and download the finished file. The whole process happens on one screen without extra dialogs.

Yes. The starting number setting accepts any value from 1 to 9999. If you enter 5, the first numbered page displays 5 and each later page counts up from there. This is useful when your document continues from an earlier file, so the numbering matches the wider set without a gap or reset.

Yes. The pages field accepts a list like "1, 3, 5-7". Only those pages receive numbers, while the rest stay blank. If you leave the field empty, every page in the document is numbered. This helps when a cover page or divider should stay clean while the body pages carry the count.

The fraction format shows the current page next to the total page count, so page three of a ten-page file reads "3/10". The tool reads the total from the document before it starts stamping. Readers can see how much is left, which is helpful in long manuals, reports, and printed handouts.

No. Numbering is applied entirely in your browser. The file is read into memory on your device, the numbers are written, and the result is offered for download. Nothing is sent to or stored on a server, so your document stays with you throughout the process.

You can pick one of six positions: Bottom Center, Bottom Left, Bottom Right, Top Center, Top Left, or Top Right. The tool measures each page and places the number at the matching corner or center. Bottom Center is the most common choice for reports, while corner positions work well for double-sided printing.

This tool only writes sequential numbers based on page order and your settings, then adds them as text layers. It does not change other content. The PDF editor lets you change text, move objects, and adjust the page contents freely. Use numbering for pagination and the editor for broader content changes.

Merge first. Numbers are stamped based on the current page order, so if you paginate separate files and then combine them, each file restarts its own count. Run the merge tool to build the full document, then add numbers so they flow continuously from the first page to the last.

Yes. The font size ranges from 8 to 36 pixels, with 12 as the default. Smaller sizes suit dense pages where you want the number to stay discreet, while larger sizes read clearly on printed handouts. The size you set applies to every numbered page across the document.

The numbers are written as text on the page, so they become part of the file once you download it. To take them out, keep your original file as a backup, or open the numbered version in the PDF editor and delete the stamped text. Working from the original is the cleaner route when it is available.
