to change
'ändern' and 'editieren' both mean that you do not leave something the way it was. 'ändern' is the more general word and fits many things: plans, rules, texts, appointments, or behavior. 'editieren' is used mainly for digital files, texts, images, websites, code, or media. It sounds more technical or professional. If you only want to say that something is becoming different, 'ändern' is more natural. If you are specifically working on a document, video, or code, 'editieren' is more precise.
