Typography Controls Select from three standard PDF fonts: Helvetica, Times Roman, or Courier. Set font size from 6 to 100 pt, choose any text color with the color picker, and set the page margin in points (1/72 inch) for precise placement.

Frequently asked questions

How do I add page numbers to a PDF?

Drop your PDF on the upload area, adjust the Layout and Format and Typography and Style settings while watching the Visual Preview, and click Add Page Numbers. The file downloads with _numbered added to its name, or with the name you type in Output Filename.

How do I change the number format, like Page 1 of 10?

In the Number Format field, every letter n inside curly braces is replaced by the page number and every word total inside curly braces by the page count, so each can appear more than once. The default prints Page 3 of 10 on page 3 of a 10-page file; delete the other words to print just 3, or 3 / 10.

Where can the page numbers be placed?

Choose one of six positions: Top Left, Top Center, Top Right, Bottom Left, Bottom Center or Bottom Right (the default). Margin sets the distance from the page edges, from 0 to 200 PDF units (points, 1/72 inch).

Which fonts, sizes and colors can I use?

Pick Helvetica, Times Roman or Courier, a font size from 6 to 100 and any color from the Text Color picker; the default is 12 pt indigo Helvetica. These standard PDF fonts only cover Latin characters, so non-Latin text in the format can cause an error.

Can I start numbering later or skip the cover page?

No. Every page is numbered, starting at 1 on the first page. To leave a cover unnumbered, split it off with the PDF Splitter, number the remaining pages, and combine the files again with Merge PDF.

Is my PDF uploaded?

No. Numbers are drawn onto the pages with pdf-lib in your browser and the file is downloaded directly on your device.
