Pretty good so far. Was a little surprised that I had to pay once all the work was done. But its okay, have used it a couple of times and its working.

Aside from the cost associated with its use, I love PDFfiller! It is easier to use than the typewriter function in Adobe Acrobat and I could place text exactly where I needed it. One other recommendation is adding a spell check when finishing up the document. Respectfully, -RPS

Following my previous comment, I found the tax forms I was working on, but they were titled by the Form, not saved documents. Taking me well over an hour due to the labeling. Need a Saved Documents Option to simplify it.

What do you like best? The most helpful thing about pdfFiller is that I can take a pdf document and add text or highlight text effortlessly. It is very user-friendly. What do you dislike? I have nothing to complain about with pdfFiller by airSlate. It saves me so much time there is literally nothing to dislike. What problems is the product solving and how is that benefiting you? pdfFiller by airSlate is solving problems when I needed to make changes to a pdf document and it was so hard to do without it looking jumbled until I found pdfFiller. It has saved me so much time and my documents come out looking so much cleaner and professional.

Great product and customer service I have been using PDF filler for two years and I am very satisfied with the product. For the first time today, I could not figure something out and sent a question to customer service. Within a very short time I got a response that solved my question. Great customer service.

best out there, has opportunities to get better generally very positive. i used the free trial for a month and switched to the yearly plan. this is by far the best pdf editor i tried using. the biggest selling point is converting the files without losing the layout and the possibility to edit copy and somewhat match the font i noticed that while editing copy the font size of the original text shifts a pixel down and the font weight automatically turns to lighter than original. still the best font matching abilities of all the tools, but sometimes a pain

Needed something to fill out a form in… Needed something to fill out a form in a hurry - it did recognise the fields, that's a plus compared with some others, LOL. Wasn't looking for any fancy features like faxing, but did the job. May only cancel IF I don't use it that much.
