I found it relatively easy to use, it would be nice if it had an undo selection. And getting the right size font was not easy. Had to wait for print out to see.

Send the PDF to iBooks. Tap the “Open in iBooks” button that appears. If you have another PDF reader, tap the “Open in” button instead then select the app. View your PDF in iBooks or your PDF reader. If you opened it in iBooks, it will be stored in the app and in your iCloud storage so that you can always access it.
Open Locked PDF Drag and drop your password-protected PDF into this tab. If your PDF file has an open password, then you will get a new window to ask for the open password.

Your iPhone or iPad is designed to open PDF files automatically. If you are having this problem with some PDF documents, it is possible that those PDF documents may be corrupted. These files cannot be opened if they are corrupted. Perhaps the PDF file you could not open was not downloaded properly.
