About Resize PDF Pages
Resize PDF Pages changes the paper size of your PDF. Choose A4, Letter or Legal and the tool sets your pages to that size. This is not the same as making the file smaller in KB. It changes the page shape so the document prints and displays the way you expect.
Offices in Pakistan and the Gulf mostly use A4, while files from the United States often come in Letter size. If a page prints with cut edges or extra white space, resize it first. Universities, embassies and offices may also ask you to submit documents on a set paper size.
