Add page numbers について
Add page numbers prints a running number on the pages of a PDF, the way a word processor fills a footer, but after the fact, when all you have is the finished file. Pick one of six spots along the top or bottom edge; the number is placed relative to the page as readers show it, so rotated or cropped pages get it in the right corner too.
The format can be a bare number, Page 1, Page 1 of 12, 1 / 12, the dashed - 1 - style or any text you type with {n} for the number and {total} for the last one, such as Exhibit A – {n}. Lower- or upper-case Roman numerals suit front matter. You can start counting at any number, for instance 37 when the file continues a longer report, and skip a cover or a title page so the first numbered page reads 1. For double-sided printing, Alternate sides on facing pages puts the numbers on the outer edges.
Numbers are written as real PDF text in Helvetica, Times or Courier, so they print sharply and can be searched. When the text contains letters those fonts lack, such as Cyrillic or the Uzbek oʻ and gʻ, a matching open font is embedded instead. Everything else in the file, including bookmarks, links and form fields, stays as it was. The tool doesn't look for numbers that are already printed, so it can't remove or replace an old sequence.
プライバシー
Your PDF is read and stamped inside this browser tab: PDF.js draws the preview and pdf-lib adds the numbers in a Web Worker, so the document is never uploaded. The only network request is for a font file from jsDelivr when your text needs characters beyond Western European letters, and it carries no part of your document.
