Editors' Review for PDF Manager - Merge, Split, Trim
This app allows you to merge, split, extract, and combine PDFs. You can also use it to add or remove passwords and insert pages into documents. This is an excellent app for managing PDFs but is not a PDF reader, so you'll need to use it in conjunction with another app on this list. Also, keep an eye for sales as it is often up to 80 percent off.
