Small Helvetica numbers in the margin. Clean, readable, no clutter.
Why bother with page numbers?
Seems like a small thing, but unnumbered pages cause real problems. Here's when it actually matters.
Court filings and legal documents
Most courts won't accept unnumbered filings. Judges need to reference specific pages during hearings, and opposing counsel needs to cite exact locations. It's not optional — it's a requirement.
Meetings and presentations
"Turn to page 14" only works when there's a 14 on the page. Without numbers, everyone's flipping around trying to find the right spot. It wastes time and makes you look unprepared.
Academic submissions
Professors and journals almost always require numbered pages. Turn in a 30-page paper without them and you'll probably get it sent back before anyone reads a word.
Client deliverables
Sending a proposal or report to a client? Numbered pages make it feel finished. It's a small detail, but clients notice when things look polished — and when they don't.
Long documents and manuals
Anything over 10 pages really needs numbers. Handbooks, guides, training materials — people need to navigate these documents, and a table of contents is useless without page references to match.

Positioning options
Four positions to choose from. Pick whichever makes sense for your document.
Bottom center
The default, and what most people go with. Numbers sit centered at the foot of each page. Works for just about everything — reports, essays, contracts, you name it.
Bottom left
Good for documents that get bound on the left side. The number stays visible even when pages are stapled or hole-punched. Common in printed reports and booklets.
Bottom right
Some people prefer this for single-sided printing. The number falls right where your thumb naturally sits when flipping through pages. It's a subtle thing, but it feels natural.
Top center
Less common, but useful when your footer area is already taken — maybe you've got copyright text or a document ID down there. Putting numbers at the top keeps things clean.
What it looks like
Small, clean Helvetica numbers. They sit in the margin area so they don't overlap your content. Page 1 gets a "1", page 2 gets a "2". Nothing fancy, just functional. The text is 10 points — large enough to read without squinting, small enough that it doesn't compete with your actual content. If you've ever seen a printed book, that's roughly the vibe. No borders around the number, no decorative dashes, no "Page 1 of 12" formatting. Just the digit, right where you told it to go.
Frequently Asked Questions
Where do the numbers show up?
Bottom center by default. You can change the position if you want them somewhere else.
Will it overlap my existing text?
It adds a small number in the margin area. Shouldn't interfere with your content unless your PDF has zero margins.
What font?
Helvetica, 10pt. Clean and readable.
Does it cost money?
Nope. Free.
Works on my iPad?
Works on anything with a browser.
Can I start numbering from page 2?
Not right now. It starts at page 1 and numbers every page sequentially. If your first page is a cover, you'd need to split the PDF first, number the rest, then merge them back together.
What if my PDF already has page numbers?
The tool doesn't know about existing numbers. It'll add new ones regardless, so you could end up with two sets. If your document already has numbers baked in, you probably don't need this tool.
Does it work with landscape pages?
Yes. The number still goes in the same relative position — bottom center, top corner, wherever you picked. It adjusts to the page orientation automatically.
Can I change the font size?
It's fixed at 10pt right now. That size works well for most documents — big enough to read, small enough to stay out of the way.
What about PDFs with existing headers or footers?
The page number goes in a fixed position in the margin. If your PDF already has text in that exact spot, they might overlap. Most documents have enough margin space that it's not a problem.
Will it number blank pages too?
Yes. Every page gets a number, whether it has content or not. The tool treats all pages equally.
Can I add numbers to specific pages only?
No, it's all or nothing. If you only want certain pages numbered, you could extract those pages first, add numbers, then merge everything back.
What if my PDF has different page sizes?
It handles mixed page sizes fine. Each page gets its number placed relative to that page's own dimensions, so a letter-size page and a legal-size page in the same document both get properly positioned numbers.
Does it handle two-column layouts?
The page number goes in the margin, not inside your content area. Column layouts don't matter — the number sits outside of all that.
Can I add 'Page X of Y' format?
Not yet. Right now it's just the number itself — 1, 2, 3, and so on. We might add format options down the road.
