Very user friendly! It is easy to use. Instructions are clear and the forms are easy to fill out accurately. I only use it once a year - at tax time, but using this program to fill out tax forms is quick and easy. I have not had any issues. I'm sure if a person uses it a lot there are bound to be some, but I use it once a year and it works fine for my uses.

Manage and edit your PDF easily and quickly. pdffiller is a pdf processor quite different from the others, you can not only convert your files from pdf to other formats (and obviously from word, excel and others to pdf), but you can directly edit and process your texts online, so which you can write about the document, underline, place images, delete phrases and all the other things that a word processor allows you to do. Another advantage and surprises that you have, is that you can use files that are not only on your hard drive, but you can also use files from the web (through the address of the document) and you can integrate pdffiller with some app that you use daily as google drive, box, one drive and others. Finally, a very remarkable feature is that once you finish editing the file, you can choose some classic options such as the format in which you save it, but it also gives you the option to share it via mail, print it, send it by fax and use it in some social networks like facebook. Even if it is a bit strange, I miss the function of compressing the files, because whenever you add images to some document, the weight of the file increases a lot and makes the handling of the file more difficult. Besides that, there is nothing more to comment.
