My uncle is a retired teacher and he writes these long Urdu notes — like 60-70 pages — and saves them as PDF to share with students on WhatsApp groups. The problem is there are no page numbers. So when a student asks “sir page 34 pe kya likha hai” he has to scroll through the entire document to find it.
He asked me to add page numbers. He thought he’d have to retype the whole thing in Word. I was like no uncle, we can just add numbers to the existing PDF. Took me about 10 seconds. He thought I was some kind of genius. I’m not. The tool is just that simple.
How to do it
Open convertkr.com/pdf-page-numbers. Upload your PDF. Pick where you want the numbers and what format. Download. That’s the whole process.
Let me break it down a bit more:
Position. You get 6 options — top left, top center, top right, bottom left, bottom center, bottom right. Most people go with bottom center. That’s what books use and it looks natural. My uncle wanted bottom right because that’s how Urdu documents traditionally do it. Your choice.
Format. Four options:
- Just the number — 1, 2, 3
- Page 1, Page 2, Page 3
- 1 of 70, 2 of 70, 3 of 70
- Page 1 of 70, Page 2 of 70
For my uncle’s notes I used “Page 1 of 70” because students want to know how far they are in the document. For something like an invoice or a short report, just the plain number looks cleaner.
Start number. This one’s useful if your PDF doesn’t start from page 1. Like if it’s chapter 3 of a book and the actual page number should start from 45. You can set it to start from whatever number you want.
Font size. Default is 12 which works for most documents. I bump it up to 14 for my uncle’s notes because he shares them on phones and small text is hard to read on a phone screen.
Click the button, wait a couple seconds, download. Done.
When you actually need this
Scanned documents. This is the biggest one for me. When you scan a bunch of pages with your phone — CamScanner, the built-in scanner app, whatever — the PDF has no page numbers. It’s just pages. Add numbers and suddenly it’s a proper document. I did this for a stack of property papers my dad needed to submit. 45 pages, no numbers. Added “Page 1 of 45” at the bottom and it looked official.
Merged PDFs. You merge 5 different PDFs into one file. Each original had its own page numbers — page 1, page 1, page 1. Now the combined document’s numbering makes no sense. Remove the old numbers? Can’t really do that easily. But you can add new numbers that go 1 through the total. Not perfect but better than the chaos of five different page 1s.
Study notes and handouts. My uncle’s situation. Teachers, professors, tutors — anyone who makes notes or handouts. Students need page numbers to reference specific content. Without them it’s just “it’s somewhere in the middle of the PDF” which helps nobody.
Reports and proposals. A friend works at a marketing agency and he was sending a client proposal as a PDF. 22 pages, no page numbers. His boss told him to add them before sending. He panicked because the original Word file was on his office computer and he was at home. I sent him the tool link, he added numbers in 30 seconds, sent the proposal, boss never knew.
Legal and official submissions. Courts, government offices, NADRA — they often want numbered pages. I’ve heard stories of people’s applications getting sent back because the pages weren’t numbered. Whether that’s true or just bureaucratic legend, I don’t know. But adding page numbers takes 10 seconds so why risk it.
Things I’ve learned
Bottom center is the safest choice. It works for every document type — reports, notes, applications, books. Nobody’s going to complain about bottom center page numbers. Bottom right is second best. Top anything looks a bit unusual for most documents but some people prefer it.
Don’t make the font too big. I see people set it to 18 or 20 and the page number becomes this distracting thing at the bottom of every page. 10-12 for printed documents. 12-14 for stuff that’ll mostly be read on phones. That’s the range.
Check the margins. The tool has a margin setting — the distance between the page number and the edge of the page. Default is 30 which is fine for most things. If your document has very small margins already and the page number overlaps with content, bump it up to 40 or 50. I had this happen once with a document that had text running right to the bottom of the page. The page number sat right on top of the last line. Increasing the margin fixed it but then the number was really close to the edge. In those cases there’s not much you can do — the original document just doesn’t have room.
Start number matters for chapters. If you’re numbering chapter 2 and chapter 1 ended on page 30, set the start number to 31. Otherwise chapter 2 starts from page 1 again and anyone reading the full book gets confused. Seems obvious but I’ve seen printed books get this wrong.
Can’t I just do this in Word or Google Docs?
If you have the original editable file — Word, Google Docs, whatever — then yes, add page numbers there and export as PDF. That’s the proper way.
But most of the time you DON’T have the editable file. You have a PDF someone sent you. A scanned document. A merged file. Something you downloaded. You can’t open a PDF in Word and expect it to look right — Word messes up the formatting, moves things around, changes fonts. I’ve tried. It’s a disaster every time.
For existing PDFs that you can’t edit, adding page numbers with a tool like this is the only clean option. The original content stays exactly the same — you’re just adding small numbers to the margin area.
FAQ
Will the page numbers overlap with my content?
They go in the margin area outside the main content. But if your document has very tight margins or content that goes to the edge of the page, there might be some overlap. Adjust the margin setting in the tool to push the numbers further from the content. Preview it before downloading to check.
Can I remove page numbers from a PDF?
Not easily. Page numbers get baked into the PDF. If you need to remove them, you’d basically need to cover them with white rectangles using the PDF editor. Not ideal but it works in a pinch.
Does it work on scanned PDFs?
Yes. Scanned PDFs are just images inside a PDF container. The tool adds page numbers on top regardless of whether the pages are text-based or image-based. Works the same.
Can I add numbers to only some pages?
Right now it adds numbers to all pages. If you want to skip the first page (like a cover page), you’d need to split the PDF first, number the pages without the cover, then merge them back. A bit of a workaround but it takes a minute.
