Delete pages in a PDF document

You can delete specific pages from a PDF file with the built-in Mac Preview app, just select/highlight the page you want to delete and then hit the delete key. This is really useful for paring down large PDF documents if you only need a few select pages, this is bound to make any student or researchers life easier when emailing or printing documents.

In the above screenshot example, I have deleted multiple unnecessary pages within a research PDF document before I printed it, my school charges for each page so reducing the printed page count is particularly valuable. You’ll notice that the PDF page numbers don’t change though, which is both good in that you can quickly identify which pages are missing, and bad if you are hoping the pages would reorder themselves after others were deleted.
