How do I start numbering after the cover page?
Type 2- in Pages. The cover gets nothing and the page after it is numbered 1. If the cover should still count as page 1, set the first number to 2.
Can it do Bates numbering?
Yes. Type a prefix before {n}, set the digits to 6 or 8, and turn on carrying the count on from each file to the next. The arrows on each row set the order.
Why do page numbers land in the wrong place in other tools?
A PDF page can be stored turned or cropped, or with its coordinates left scaled by its own drawing, as scans often are. This tool measures from the page as shown, undoes what the page left open, and reads the copy back to see each number where it was put.
Is my file uploaded?
No. The PDF is opened, numbered and checked in your browser, and nothing is sent anywhere.
