Add page numbers to a PDF

No. The tool runs entirely in your web browser using JavaScript. Your files are read from your device, processed in memory and saved straight back to it. They are never uploaded, stored or seen by anyone.

Yes. The preview shows the first page you’re numbering with its number where it will print, at the size and position you chose, and it updates as you change the options. After downloading, “Change settings” takes you back to the same PDF to adjust them.

Choose “Only some pages” and type the pages to number, such as “2-” for page 2 to the end. Numbering starts at the first page you choose, so the cover stays blank and page 2 shows the first number you set.

It’s the last number printed: your first number plus the number of pages you’re numbering, minus one. Numbering pages 2 to 10 from 1 prints “Page 1 of 9” up to “Page 9 of 9”.

Yes. Each page’s rotation and visible area are read first, so the number is upright and at the edge you chose as you see the page, even on scans that were saved sideways.

No. The numbers are marked as decoration (an “artifact” in PDF terms), which tells screen readers and read-aloud tools to skip them rather than read them out in the middle of your text. They’re drawn in the PDF’s built-in Helvetica font, which isn’t embedded in the file, so a PDF/A archive file won’t stay PDF/A-conformant once numbered.

Yes. There is no sign-up, no watermark and no daily limit. Because all the work happens on your own device, there are no servers to pay for.
