My wife had some US Government forms that needed to be filled out and returned. Because of her medical condition, she couldn't fill them out longhand, and she asked me if there was a way she could type and fill them in. We couldn't find access to a typewriter (WHAT'S THAT???), but I searched on Google and found information about your app. I had worked with some PC-based forms applications before, so I knew what type of function I was looking for. I scanned the forms into a PDF, and PDFfiller opened the files and allowed me to create editable fields on the forms which she then filled using your browser-based app. It got the job done! There were a couple times where she thought she had lost everything, but because of the automatic save function, nothing was lost. Unfortunately, I don't have any other immediate need for this, but I certainly hope you use this for promoting your product. I would have given it 5 stars had there been an apparent way of copying all the fields I added to one page and paste them onto identical subsequent pages in my document (you know the Government--lots of duplicate type information!). I had to create the same fields over about 8 or 9 identical pages on one of the forms. If I find I do have more use for this app in the near future, I will purchase it!

Great Tool! My experience has been great thus far. The use is seamless whether on my tablet, laptop, or phone, however, it's much easier to use on a laptop due to screen size. I am able to conduct business, receive faxes, scan items, edit forms, and more while on the go. This makes life a BREEZE! I am never really disconnected from work unless I choose to be. I would say the monthly payments are ongoing and never end. In real life, things like software have a finite value, however, I haven't seen an all-inclusive tool for less.

This program has great functionality This program has great functionality for myself and my team and they have excellent customer service. I switched to PDF filler nearly two years ago and have never looked back.

It got the immediate job done but there were a few hiccups. I don't particularly like their way text is displayed in the larger fill-in fields. The form I was filling out was very complicated and required numerous references to a "Remarks" section at the end of the form because there was insufficient space with the numbered questions to put complete answers without overwriting onto the next numbered question. Consequently, the Remarks section was filled necessitating a separate attachment to contain all the remarks. In the remarks section, I cross-referenced to the numbered question for clarity, e.g. "Question 12(b)..." When I viewed the form on the screen the formatting looked fine but when it printed, the "Q" in the word Question was on one line and everything else "question 12(b) was on the next line. I would like to know how to avoid that issue in the future.

When I chatted with support When I chatted with support, I had had two different people who took the files I had been trying to merge unsuccessfully and merge them for me!!! Similarly when I had trouble with blank pages and missing pages in a merged document I found out it was because I was using Edge as my browser instead of Chrome. It would have been best if that had been in the program itself, but support really came through to help me out.

It was a little challenging at first and the online help was a little overbearing to start. You should always assume that people know how to operate every aspect of there computer. I had a glitch and he was a little belittling to me which being 50 and having diabetes its hard for me to see sometimes and once i stated that his demeanor changed and he helped me finally.
