What do you like best?
Ability to use templates was the most helpful. I like PDF filler because I can encrypt and decrypt documents, merge PDF files, crop or rotate PDF pages. It's fairly easy to use but the interface isn't great.
What do you dislike?
The user interface is not intuitive for me. I liked all other features and don't have much bad to say. I'll continue to refer people.
