About adding page numbers
Page numbers make a long document easy to reference, print, and assemble in the right order. This tool draws a small label onto each page of your PDF without re-rendering the rest of the content, so the original text and images stay exactly as they were. You decide where the number sits, how it reads (just the number, the number with a total, or the word Page in front), what value it starts from, and how large the text is. The result is a new PDF that looks the same in every viewer, now with a clear number on each page.
Is it private?
Yes. The numbering runs entirely in your browser using pdf-lib, a pure-JavaScript library. Your file is read into memory, the numbers are stamped on-device, and the download is built locally. Nothing is uploaded, stored, or seen by us, and there is no server to send files to.
Frequently asked questions
- Is my PDF uploaded to a server?
- No. The page numbers are stamped on your device using pdf-lib, a pure-JavaScript library. Your file is never sent anywhere, and there is no server involved.
- Where can the page number go?
- You choose. The number can sit at the bottom or top of every page, aligned to the left, center, or right, so it fits the layout you already have.
- Can I start numbering at a value other than 1?
- Yes. Set the starting number to anything you like, which is useful when a document continues from an earlier part or skips a cover page.
- Can I skip the cover or leave some pages unnumbered?
- Yes. Tell it how many pages to skip at the start and at the end, so a cover and a back page can stay blank while the rest are numbered.
- Does it work for a printed book or booklet?
- Turn on facing pages and the number mirrors to the outer corner — right on odd pages, left on even ones — so it reads correctly once the sheets are bound double-sided.
- Is it free, and do I need an account?
- It is free with no watermarks, no daily caps, and no sign-up. Drop a file, choose your options, and download the numbered PDF.
