MarsPDF provides an intuitive, browser-based Number PDF tool to add page numbers to your PDF documents instantly and securely.

Our tool operates completely in your web browser, allowing you to generate numbered PDFs without any sign-up, payment, or software installation.

How to Add Page Numbers to PDF
Upload PDF File
Drag and drop your PDF document into the upload zone above, or click the choose button to select a file from your device.
Configure Number Settings
Choose page number position, format style, start number, font, text color, margins, and select whether to skip the first page.
Download Document
Click "Number PDF" to process. Your numbered document will render in seconds, ready for high-speed download.
Choose Page Number Position
Select exactly where you want the page numbers to appear on the document canvas. We offer a 6-option positioning grid allowing you to stamp page numbers in the header or footer areas:
- Top Alignments: Stamp numbers in the top-left corner, top-center header, or top-right header of your pages.
- Bottom Alignments: Apply numbers to the bottom-left corner, bottom-center footer, or bottom-right footer of your pages.
Customize Number Format, Font, Color, and Margins
Our tool offers advanced formatting flexibility to ensure page numbers integrate seamlessly into your document style:
- Number Formats: Choose standard integer counting (1, 2, 3), prefix formatting ("Page 1", "Page 2"), suffix formatting ("1 of N", "2 of N"), or full pagination ("Page 1 of N", "Page 2 of N").
- Typography: Match your corporate document design using clean standard fonts such as Helvetica, Times Roman, or Courier. You can adjust the font size dynamically.
- Text Color: Use our visual color picker palette to set the page numbers' shade from classic black or gray to bright customized color tones.
- Margins Control: Fine-tune padding boundaries. Adjust top, bottom, left, and right margins in pixels to keep the numbers centered and within print borders.
Skip First Page or Number All Pages
Most formal publications, reports, and books use a cover page or a title page that does not require pagination. With MarsPDF, you can easily check or uncheck the "Apply to all pages" option. By unchecking it, you can skip the cover sheet and start the page numbering sequence from the second page. This keeps your document clean and professional.

- Print-Ready Structuring: Prevents confusion when documents are printed, ensuring paper sheets can be collated and bound correctly.
- Professionalism: Essential for academic journals, legal briefs, pitch decks, and financial presentations.
