How to Add Page Numbers to PDFs
If you have a large contract, legal brief, or manuscript that is missing pagination, it can be incredibly frustrating for readers to reference specific sections or maintain their place over hundreds of pages. Our digital page numbering tool instantly loops through your PDF and stamps sequential pagination at the bottom center of every page.
Numbering your Document
Pagination happens automatically with zero configurations required from you:
- Upload a File: Select the PDF document you want to stamp from your device or drop it into the upload box.
- Automatically Process: Click the "Add Page Numbers" button. The tool algorithmically analyzes the total length of the document and stamps "Page X of Y" across every page.
- Save and Download: The script will zip through hundreds of pages in milliseconds, immediately triggering a download prompt.
Universal Compatibility
The page numbers applied to the document use standard PDF drawing commands. This ensures that no matter what device or software the recipient uses—Apple Preview, Adobe Acrobat, Foxit, or Google Chrome—the numbers will display clearly with 100% interoperability.
Why Use Our Numbering Tool?
100% Private Processing
Unlike other PDF tools that force you to upload your sensitive documents to a remote server, our tool works entirely within your web browser using client-side WebAssembly. The files remain strictly local on your device.
Total Accuracy
Our parser guarantees 100% accurate page counts and numbering. It automatically detects the width of every document dynamically, stamping the pagination directly in the bottom dead-center.
No Hidden Limitations
We don't limit how many times you can use our tool, nor do we restrict the file size to try and upsell you. You can freely number massive, 1000-page scanned documents completely free of charge.
Instant Processing
Due to our client-side architecture, the processing is nearly instantaneous. You don't have to wait in queues for a cloud server — your numbered file is ready to go instantly.
