Need to edit a PDF on the go? Apple recently added a few light duty editing tools directly to the Files app. In addition to annotation, iOS users can rotate PDF pages, insert and delete pages, and even scan new content. Once edited, the PDF can be saved and shared. Files may not replace the capabilities of Adobe Acrobat, but it can be helpful in a pinch.
