VUISO ADD PAGE NUMBERS — how to use =================================== Put page numbers on a PDF, in the corner you choose, and see the exact number every page will get before you save. Everything happens inside your browser. Nothing is uploaded, there is no account, and it works with the network switched off. This tool works on ONE FILE at a time, and it numbers the pages in the order they are already in. To combine several files first use Vuiso Merge PDF; to put pages in a different order use Vuiso Organize PDF. Number last. OPENING IT Double-click "Vuiso Add Page Numbers.html". It opens in your browser like a normal page. There is nothing to install. Chrome or Edge is recommended; Firefox and Safari work too. THE SHORT VERSION 1. Open PDF (or drag the file onto the page area) 2. Pick a format 1, Page 1, 1 / 10, Page 1 of 10, or your own 3. Save PDF The pages on the right already show the result, and under each page is the exact text it will get. Nothing is written until you press the button in the Save window. WHAT THE NUMBER SAYS Format 1 Page 1 1 / 10 Page 1 of 10 - 1 - or Custom, where you write the text yourself. Custom text {n} is replaced by the number, {total} by the last number. "Page {n} of {total}", "Hal. {n}", "{n} | Annual Report 2026" all work. Choosing Custom starts from the format you had, so you only have to change what is different. Number style 1, 2, 3 or i, ii, iii or I, II, III Start at the number on the first numbered page. 1 by default. The ready-made formats follow the tool's language: switch to ID and "Page 1 of 10" becomes "Halaman 1 dari 10", in the preview and in the file. HOW THE COUNT WORKS Numbers count up over the pages that GET one, starting from "Start at". {total} is the last number actually written, so "Page 9 of 9" is always true of the file you save. A cover without a number: Number which pages = Every page except the first. The second page becomes 1. A cover that still counts: the same, with Start at = 2. The second page becomes 2. HOW IT LOOKS Typeface six built-in faces: Helvetica, Times and Courier, each in regular and bold. They need no font file, which is why the whole tool is one small page. Size 6 to 72 points. 10 or 11 is what most printed documents use. Colour any colour, with four common ones one click away. WHERE IT GOES Where on the page top or bottom; left, centre or right. Distance from edge how far the number stays in from the edge, in points (72 points = 1 inch, 28 points is about 1 cm). It is measured to the ink, so a top number and a bottom number sit the same distance in. Swap left and right on even pages for a document printed double-sided and bound: the number stays on the outer edge of every sheet. Pages 2, 4, 6 in the file get the other side. Has no effect on a centred number. WHICH PAGES Every page the default. Every page except the first leaves a cover or title page clean. Selected pages the ones you click in the grid. A range I type 2-10, 12- A trailing dash means "to the end". A page that will not get a number is greyed out and says "no number" under it, so a range typed wrongly is visible immediately rather than after you have saved. SELECTING PAGES Click select one page SHIFT + click select everything between it and the last one clicked CTRL + click add one page, or take one out of the selection CTRL + A select every page Esc select nothing Clicking a page while "Every page" is set switches to "Selected pages" for you, and says so - otherwise the clicking would have done nothing. THE ONE THING WORTH UNDERSTANDING A scanned page usually carries a rotation of its own, recorded inside the PDF, so the page you SEE is not the page as it is stored. The number is placed against what you see, then translated onto the stored page, which is why a footer lands at the bottom of a sideways scan and reads level, instead of running up its side. The same goes for a page that has been cropped: the number is placed inside the part of the page that shows, not the part that was cut away. SAVING "Save PDF" shows a summary first: the source file, the first and last number that will be written, and how many pages get one. Nothing is written until you press the button in that window. Your original file is never modified. The new file is your document with the numbers drawn onto it - bookmarks, links, form fields and text all survive, and a searchable PDF stays searchable. Nothing is re-encoded. The numbers are real text drawn into the page, not annotations, so they print and they can be searched. A page that already had a number printed on it keeps that one too: this tool adds, it never erases. KEYBOARD SHORTCUTS Ctrl+O Open PDF Ctrl+A Select every page Esc Select nothing Ctrl+E Save PDF NOTES - The six built-in typefaces cover Latin letters, which is what the PDF standard fonts carry. Write something in Custom text they cannot show - Japanese, Arabic, Cyrillic - and the tool says so, and names the characters, instead of failing at save time. - Roman numerals stop at 3999. A number past that is written in ordinary digits. - Big documents open immediately. Thumbnails are drawn only as they scroll into view, and the cache holding them is capped. Changing a setting redraws from that cache, not from the file. - Memory, as a rough guide: allow about 300MB plus several times the size of the file. If it ever runs out the browser closes the tab, and because your original is never written to, you lose the settings and nothing else. - Nothing is stored. No cookies, no database - closing the tab loses the settings, which is why there is a warning before you do. The only thing remembered is which of the two languages you chose. PRIVACY The file contains a Content-Security-Policy that forbids network connections entirely. That is enforced by the browser, not promised by us: open DevTools, watch the Network tab, and it stays empty. You can also disconnect from the internet and the tool still works. Verify the copy you hold matches the one published: Windows Get-FileHash "Vuiso Add Page Numbers.html" -Algorithm SHA256 macOS/Linux shasum -a 256 "Vuiso Add Page Numbers.html" Compare the result with the SHA-256 printed on the download page and in the .sha256.txt file next to this one. LICENCE See LICENSES.txt, which must stay alongside the tool.
