How Do I Remove Page Numbers, Headers and Footer?
Page numbers appear either in the header area or the footer area. To remove page numbers, remove either the header where the page number appears or the footer where the page number appears.
Remove Header+Footer:
1. Choose Edit > Page Numbers, Headers, Footers. Then click “Remove Header” or “Remove Footer.”
If you hold down the Option key you can remove page numbers from the whole document instead of just from the selected page.
