Skipping the cover
Set "First page to number" to 2 and "Start at" to 1. The cover stays clean and numbering starts at 1 on the second page. To skip a contents page as well, start on page 3.
Rotated pages are numbered the way they appear on screen, so numbers never end up sideways. Numbers are set in Helvetica.
Your files never leave your device
Most online PDF sites upload your file to a server, process it there and send it back. Pagefold loads the PDF engine into your browser and does the work on your own device. Contracts, ID scans and school records stay with you, and there is no upload to wait for on a slow connection.
