Add Page Numbers to PDF

Make PDFs Easier to Reference and Print

Scans, merged documents, and PDFs exported from web pages often lack continuous page numbers, making it difficult to point readers to a specific location. This tool adds numbers directly to the top or bottom of each page. Choose from 1, Page 1, or Page 1 of 10, and customize the alignment, font size, color, and page range. The numbers become visible page content, so they appear in common PDF readers, on mobile devices, and in print.

Adding numbers does not change the original page order or detect printed page numbers already in the document. If the file already has numbering or a footer, choose another position to prevent overlap. To leave a cover page unnumbered, apply numbering from the second page onward. The displayed numbers will still follow the PDF's actual page order.

Choose a Format, Position, and Page Range

Choose “1” for simple numbering, “Page 1” for a labeled format, or “Page 1 of 10” to show readers the total number of pages in a long report. Bottom center works well for most portrait documents. For bound documents, place numbers near the bottom outer edge; if a footer is already present, use the top instead. A 10–12 point font is usually suitable for A4 pages, while posters and larger pages may need a larger size.

You can specify individual pages, continuous ranges, or a combination, such as 2-8 or 2-5,9. Leave the field blank to number every page. After processing, download the PDF and inspect the first page, the boundaries of each selected range, and the final page. Make sure the numbers are not too close to the trim edge and do not cover QR codes, footnotes, or signatures.

Reports, Handouts, Scanned Records, and Merged PDFs

Adding “Page x of y” to a project report helps reviewers confirm that the document is complete. Simple numbers keep classroom handouts uncluttered. Numbered scans are easier to match with a table of contents or index. Renumbering a PDF assembled from multiple sources also prevents confusion when each source document starts at page 1. When uploading multiple PDFs, numbering starts independently from the first page of each file.

If you need Roman numerals, chapter-based numbering, a cover page excluded from the count, or a custom starting number, this streamlined tool may not be sufficient. Use professional publishing software that supports advanced header and footer rules. Page numbers assist navigation but do not update a table of contents within the document. If the existing contents page uses fixed page references, you may need to recreate it.

Common Questions About Starting Pages, Page Totals, and Printing

Check Signatures, Trim Areas, and Final Output

Adding page numbers modifies the PDF and will usually invalidate existing digital signatures, so sign the document only after finalizing the numbering. Numbers may be cut off if the margins are too narrow or the pages will be trimmed later. Complete all cropping and page reordering before adding numbers. Documents intended for formal publication, legal submission, or duplex binding must also follow the recipient's requirements for placement, font size, and starting number.

Do not rely solely on browser thumbnails after processing. Download the file and inspect it in the PDF reader and print preview you plan to use. Keep the original so you can generate a new copy if the position or range is incorrect. Page numbers are not a tamper-prevention measure; use digital signatures, hashes, or controlled archiving to verify integrity. If the document mixes portrait and landscape pages, check the number placement on each orientation when viewed at the correct rotation.

Page-number text may conflict with the document's trim box, bleed area, or a printer's non-printable margins. Before processing a large batch for formal delivery, create a sample and confirm that the recipient accepts the format. Consider adding “numbered” to the filename to distinguish the output from the unnumbered original.
