easiest way to fill forms! I like it and I recommend it to anyone who works with Forms that cannot be edited using another softwares. In my job we need to complete a LOT of forms (we are a law firm specialized in tax and corporate law so we need to complete a lot of forms that come in PDF format) and some of them doesn´t allow us to make any edit in the regular PDF program so PDFFiller is our salvation. It is super easy to use and it allows you to edit the entire document using only this software. You can add text or even delete parts that you don´t need. It is a software that doesn´t require any effort to understand because everything is as simple as upload the document, make the changes and save as pdf or print the document. I use it every day and I find it very complete for the things that I need. You are not able to use it in several computers, so if by mistake you open your session on another computer you may loose your work.

I have used PDF filler often to complete PDF forms. The program is very user friendly. I love it! I love the ease of use it creates when completing documents. It takes the hassle out of completing some of the complicated documents. I really don't have any negative feedback about the software. Sometimes the text of the document overlaps and I have not figured out how to avoid that from happening.

I'm a little bit new at the process, but I'm interested in learning as much as possible about any new technologies, that will save me a little bit of time.

I used it for my rental application and lease. The app at times was very slow to open. that's why I rated it a 4/5. Other then that it was easy to use.

I thought I only needed this temporarily I thought I only needed this for an isolated use, but found it was much more useful in future applications. I appreciated it in a pinch.
