PDFfiller! This software overall is really well done. I prefer to use it when compared to other PDF filling software. It is also free, which is even better. This software does all the hard work for you. It recognizes each possible area for text, and understand if there is an area for a diagram/picture/drawing instead. This software gives you multiple different ways to input your signature as well, which is always something I look for when it comes to similar software. Grammarly also works moderately well with this software, if that is something you use. PDFfiller looks very busy. Even though it is relatively easy to use, it can seem daunting when you first start using this software.

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.
