PDFfiller is allowing me to save time and paper filling in documents that are received in PDF form to be completed and resent in a timely manner. This make for better office management and efficiency.

I appreciate the different features to edit the documents. I primarily used it for my studies, where I have to closely read a large amount of texts and am not always able or willing to print them (also due to ecological reasons). However something that annoyed me somewhat is the fact, that one can not edit the font of individual words in a textbox. For example when I want to underline a specific word in a sentence, it automatically underlines the whole passage.
