Sometimes a PDF is right except for one page: a cover sheet, a blank scan, a page with someone else's details on it. Give me the PDF and mark the pages you don't want. Tap them, or type something like 2, 4-5 — that marks three pages — or mark every odd or even page in one go. They stay where they are, dimmed, so you can still see what you are about to remove, and tapping again takes the mark off. The line under the field tells you how many pages go and how many stay. When you save, I write a new PDF with the remaining pages in the same order and leave your original file untouched. It all happens in your browser: the file is not uploaded and stays on your device. Two things I won't do. I won't save a file with no pages left. And if a page you marked holds form fields, I'll stop and tell you: removing that page doesn't guarantee its form data is gone from the file, so I'd rather you unmark it than send something you didn't mean to.
