Numerous other options to edit documents


In between the ‘pencil tool’ and the ‘shape tool’ is the option to add text, which is useful if you are filling out a form. On top of that, you can redact existing content, add an electronic signature, comment, and print PDF files with existing comments, straight from our editor.

Remember, whenever you need to remove an added element, switch back to the ‘Select’ tool (the shortcut is ‘Esc’) to select and adjust individual sections. Furthermore, remember to be on the exact page that you wish to draw on, to prevent the need to move drawings between pages.
