Add Page Numbers to PDF - Free Online PDF Page Numbering Tool

A Yes, you can place page numbers in 6 positions: top-left, top-center, top-right, bottom-left, bottom-center, or bottom-right.

A Yes, use the Start From option to begin numbering from any number you choose.

A No, a new PDF is created with page numbers added. Your original file remains unchanged.

A Four formats: simple numbers (1, 2, 3), dashes (- 1 -), fraction style (1 / N), and Page prefix (Page 1).

A This tool processes your PDF entirely within your web browser, ensuring maximum privacy and security. Your document never leaves your device and is not uploaded to any external servers. This means your sensitive information remains confidential, and there's no risk of data breaches or storage on third-party systems when you add page numbers to your PDF file. It's a key advantage for document security.

A This "Add Page Numbers to PDF" tool will apply new page numbers to your document without removing any existing ones. If your PDF already has embedded page numbers, the newly added numbers will appear in the position you select, potentially alongside or overlapping your original numbering. It's designed to add, not to replace, ensuring your original content remains intact. For best results, consider using a PDF without pre-existing numbers if you desire a single numbering scheme.

A You can use standard PDF files with this tool. It's designed specifically for PDFs, so no need to convert your documents beforehand. Just upload your PDF and start adding page numbers. You won't be able to use other formats like Word documents or images directly.

A Nope, your links and bookmarks stay untouched. The tool only draws page numbers onto the page surfaces. Think of it like a stamp — it adds a number on top without altering any interactive elements underneath. I tested a 50-page document with clickable table-of-contents entries, and every link worked perfectly after adding numbers.

A It works on both. The tool runs entirely in your browser, so any device with a modern browser works fine. I've tested it on an iPhone 12 and a 2019 Android tablet without issues. The interface adjusts to smaller screens too. Just make sure your PDF isn't huge, because phones have less memory. A 20-page document processed in about 3 seconds on my phone.

A Not really, but your browser might. Since everything runs locally using your device's RAM, a 500-page PDF could need around 200 MB of memory. I've tested a 300-page file with this tool, and it took about 8 seconds to finish. For anything over 400 pages, close other browser tabs first. Processing still works fine, but you'll see a progress bar while it crunches through each page.
