Like that it remembers where I was in filling in the forms. Filling in was a little awkward on the government forms I was working with. Would help to have a built in tracking mechanism to determine progress.

I'm just beginning and not sure I'm using it correctly. what I'd like to do is to be able to simply use the icon in my internet task bar to open the account rather than have to open up pdffiller.com

My work with clients made EASY! This has made my work with mental health clients so much easier. I am able to convert any document to a "Fillable" PDF so that the client doesn't have to work so hard to complete assignments and assessments! Thank you!!!

The platform is sleek and elegant and allows you to work and manipulate PDFs in the easiest of forms. Of all the programs I look into, PDFFiller is the one I found the easiest to use.

The reason it is a four instead of a five... The reason it is a four instead of a five is I feel like there is a strong learning curve... at least for me. So I am still learning. Check back with me in a month and let's see if we can delete this 4 rating and move it up to a 5!!

It served my purposes It served my purposes. There were a few instances where it would not properly let me check a box. Also, inputting dates, did not always work as expected. I was not always able to manually type in a date. It forced me to use the calendar. Sometimes. It's a good tool.

Super product, it takes but a few minutes to master and then you are off. The ability to change original self-fillable documents is a terrific feature.

I didn't know a service like this existed but it is so convenient and safe or what is happening with the COVID-19 pandemic. I was able to mail very important documents without leaving my home.
