I have only used this once so far but it was very good quality. I hope to be able to utilize this program often. I just wish it could be put on my desktop.

Very easy to use. Great for completing Government forms. Minor mistakes easily corrected and the end result is much neater and legible. Saves time and paper by not having to print forms, complete them manually then scan the completed form.

Hard to get used to, and probably a lot of features we are not taking advantage of for lack of know-how, but very reliable and handy. We mostly use it to send for signature.

PDFfiller Review
I love that I can pull up any pdf form and fill in the blanks. I do a lot of work with the postal forms and this has been so helpful with keeping the information.
I wish you could just double click on a form and open the file, but nothing other than that

I am not computer techy
I am not computer techy - and I have been able to figure this out to do what we need. I am sure there are features that I have not figured out yet - but I stay very busy @ work so doing a webinar would be tricky to schedule.
2020-07-21
It was very easy to navigate the site and fill out the form I needed. I like that they have several options available to print, email, fax and even send out a copy USPS.
