Your file never touches our disk.This tool works entirely in memory and hands the result straight back in the same response — unlike the other tools on this site, there is no 45-minute copy sitting on our server afterwards, because none is ever written.

A report that needs page numbers before it goes out, or a document that has to continue the numbering of a printed original. Set where it starts and where it sits, and every page gets numbered. Nothing is re-compressed — the existing text and images are untouched.
The first page gets your start number, and every page after it counts up by one. A 12-page file starting at 5 ends on page 16 — useful when this document picks up where a printed original left off.
Bottom centre is the common default for reports and books. Bottom left or right keep the corner clear for other stamps; top centre suits a running header instead of a footer.

Numbering a document you are about to send out? Add a watermark first if it also needs a CONFIDENTIAL or DRAFT stamp. Only need to number part of a bigger file? Split PDF pulls out the range first.
Drop the PDF in, set the start number and position, and press Add page numbers. The download has a number printed on every page, counting up from the start you chose.
Yes. Type any start number — useful when this file continues a document that was already numbered up to a certain page elsewhere.
Bottom centre by default. Bottom left, bottom right and top centre are also available.
No. It only adds a new number; it does not detect or remove numbers that were already part of the page content.
No. Only a small number is added to each page — the existing text and images are untouched.
25 pages per file. There is no account, no watermark and no daily cap.
