Hello! I know there is a similar post already but I can only ask for help. I'm a student and got the courses for the semester and we should be able to do anything we want to do with it, the material got distributed online due to recent events, but somehow I can't copy the relevant parts and formulas for the project and definitions for the course applications due to the watermark, since we need to hand the asignments online. Acrobat can detect the caracters and remove them but I don't want to remove every character detected, one by one, manualy, from a 250 page text pdf. Can someone give me some advice?
