What you can do with Add Page Numbers
Adding page numbers stamps sequential numbers onto a PDF's pages, so a printed or shared document is easy to reference, keep in order, and cite.
Number a long report
Add page numbers to a report or thesis so readers and reviewers can point to a specific page.
Keep printouts in order
Number pages before printing a big document so they are easy to reassemble if dropped.
Prepare official documents
Add numbering where a submission requires clearly paginated pages.
Reference in a meeting
Give everyone the same page numbers so "turn to page 12" works for the whole room.
A more secure model for Add Page Numbers
The weakest point in most online PDF workflows is the round trip to a server: the upload can be intercepted, the server can be compromised, and copies can linger in logs, caches, or backups long after you are done. Adding TLS helps in transit, but it doesn't protect the copy that ends up sitting on the provider's disk.
ContinuePDF's approach is to not send the file anywhere. The number logic runs inside your browser's sandbox, isolated from other sites and from the wider system. Your PDF exists only in your device's memory while the tool works, which shrinks the attack surface to essentially zero — there is no server component to breach.
Why choose ContinuePDF
No transmission
The file is never sent over the network, so it can't be intercepted.
No retention
Nothing is stored server-side — no logs, caches, or backups of your file.
Sandboxed
Processing runs inside the browser's isolated security sandbox.
Minimal surface
No server component means there is nothing on our side to attack.
Pro tip
Choose a position and format that will not clash with existing content — bottom-centre or bottom-right is standard — and, where possible, start numbering after a cover or contents page. Preview to make sure numbers do not overlap footers.
Frequently asked questions
Can I control where the page numbers appear?
Yes. You can place them at the top or bottom and choose the alignment, so they fit your document's layout without covering other text.
Can I start numbering from a specific page?
Typically yes — useful when a cover page or table of contents should not count, so page 1 lands where the main content begins.
How is this more secure than other Add Page Numbers tools?
Most tools upload your file to a server, creating a copy that can be intercepted, logged, or breached. ContinuePDF processes your PDF inside your browser, so the document is never transmitted and no server-side copy is ever created.
Are my files stored anywhere after I number them?
No. Because the file never leaves your device, there is nothing stored on our end. The document lives only in your browser's memory during processing and is cleared when you close the tab.
Is ContinuePDF free to use?
Yes. ContinuePDF and all of its tools, including Add Page Numbers, are free with no signup required. Because documents are processed in your browser rather than on our servers, we can offer the full feature set at no cost.
