Add Page Numbers to PDF PDF Tools
Need to add page numbers to your PDF? You have come to the right place. Whether you are working on a single report or managing a stack of legal discovery files, getting your documents properly paginated should not feel like a chore.
Here is the good news: with AFFLIGO, you can number your PDFs in under two minutes. No software to install, no account to create, and absolutely no uploading your files to some random server. Everything happens right in your browser.
We built this tool because we have been there ourselves. We know how frustrating it is when a simple task like adding page numbers turns into a half-hour ordeal of downloading software, figuring out confusing interfaces, and worrying about whether your confidential files are sitting on someone else's cloud. That is why we made it dead simple and completely private.
Quick tip from our team: Most professional documents look best with 10pt Helvetica at about 70% opacity. It is subtle, clean, and does not distract from your actual content. Want to go deeper? Check out our complete guide to PDF pagination where we break down advanced techniques used by legal professionals and publishers.
Why Professionals Choose AFFLIGO for PDF Pagination
Let us be honest. There are dozens of tools out there that claim to add page numbers to PDFs. So why do legal teams, academic researchers, and publishing professionals keep coming back to ours?
It comes down to three things: precision, privacy, and speed.
Your Documents Stay on Your Computer. Period.
We built this tool using WebAssembly (Wasm), which means every single byte of processing happens inside your browser. Your PDF never touches our servers. Not even for a second. For lawyers handling discovery documents, doctors managing patient records, or researchers working with unpublished data, that level of privacy is not a nice-to-have. It is essential.
No Quality Loss. Ever.
Most free online PDF tools work by converting your document into an image, slapping text on top, and re-saving it. The result? Blurry images, broken text selection, and files that are somehow larger than when you started.
We do things differently. Our vector-injection engine adds page numbers as a clean, transparent vector layer directly on top of your existing content. Your images stay sharp. Your text stays selectable and searchable. And your file size barely budges.
Batch Process 20 Files in One Go
If you have ever had to paginate a hundred-page legal brief or a multi-chapter thesis, you know how tedious it gets. Our batch processing lets you drag in up to 20 PDFs at once, apply the exact same styling to all of them, and download everything in one shot. Same margins, same font, same positioning across your entire document set. Consistency matters, especially when you are submitting to a court or a journal.
Works with Any Page Orientation
Got a document that mixes portrait pages with landscape charts? No problem. Our layout engine detects the orientation of every single page and automatically adjusts the number placement so it always looks right. No manual tweaking required.
Complete Control Over Placement
Sometimes you need your page number dead center at the bottom. Sometimes it needs to sit in the top-right corner, nudged 12 pixels to the left to avoid overlapping a watermark. Our X-Y offset controls let you position numbers with pixel-perfect accuracy. You are not locked into presets. You get the exact look you want.
Bates Numbering for Legal Work
Lawyers and paralegals will appreciate our built-in Bates numbering support. Set your prefix, starting number, and digit length, and the tool handles the rest. Perfect for discovery, deposition transcripts, and trial prep.
Once your PDFs are properly paginated, you might want to compress them to shrink file sizes for email, merge multiple files into one clean document, or split out specific pages you need separately. All with the same privacy-first, browser-based approach.
How to Add Page Numbers to Your PDF in 3 Simple Steps

Step 2: Customize Your Settings

Just drag all your files into the upload area and apply the same settings to every document at once.
Not at all. We use a non-destructive vector-injection engine that adds page numbers as a transparent vector layer on top of your existing content. Unlike tools that convert your PDF to an image and re-save it, our approach keeps your high-resolution images crisp and your text fully searchable. You will not see any quality loss, even on print-ready documents.
Absolutely. Built with WebAssembly (Wasm), all processing happens directly in your browser. Your files never leave your computer or get uploaded to any server. This provides complete privacy and security for sensitive legal, financial, or medical reports. Even we cannot see your documents.
Yes. Use our Skip feature to ignore the first page or any number of pages, and set a custom starting number. This is perfect for documents with cover letters, table of contents, or when continuing a sequence from a previous volume. You have full control over where numbering begins and which pages get numbered.
Yes, our smart layout engine automatically detects the orientation of every page. Whether your PDF has standard portrait pages or wide landscape blueprints, page numbers automatically adjust their coordinates to stay perfectly aligned and visible. You do not need to process portrait and landscape pages separately.
Yes, you have full control. Choose from multiple professional fonts, adjust size and opacity, and use X-Y offset controls to position page numbers pixel-by-pixel. This ensures you can avoid overlapping with existing content, professional footers, or watermarks. Most users find that 10pt font at 70% opacity in the bottom center gives a clean, professional look.
Bates numbering is a sequential numbering system used in legal documents where each page gets a unique identifier, typically formatted as a prefix followed by a sequential number (for example, ABC-0001, ABC-0002). Our tool supports full Bates numbering customization including prefix text, starting number, and digit padding. This is essential for legal discovery, deposition transcripts, and court filings.
