pdfFiller scores top ratings on review platforms
Experience was OK. Site is not clear on how to change type size and document size when filling in form. Also don't appreciate having to use PDFfiler and pay for a subscription just to save my document and print a copy. It contradicts your advertising for a Free service.
Performance is slow and choppy at times. There is no OBVIOUS way to turn off the popups every single time I go to fill out a form. Transitioning from one form to another is extremely disjointed. There is no clear way to fill out one form and simply move on to the next in a series. If there is a clean workflow in there somewhere, it's not obvious, at least, not for my use case, which is to fill out a form for each of my employees from a remote location, download all and print all for distribution. Seems like every time I finish something, it takes a while to save, and a while to get to the page letting me choose what to do next, which is always to display the file list again, and a while to load the file list. . .rather than simply keeping the filelist persistent and hidden, as would seem same here. Also, this form, won't let me enter more than a character or 2 before kicking me out. I am writing this feedback in a notepad and then copying it in all at once. Awesome.
Probably just me, but having trouble creating a fillable form and saving to my computer. Will keep exploring!
I have since figured out more basics!
I had a problem with a pdf file freezing up on deadline and not being able to copy it when I was on deadline. I have to say, though, your online customer service was extremely helpful in solving my problem.
Customer service are extremely…
Customer service are extremely efficient. I had an issue, it was dealt with within an hour. Could not ask for better customer service.

I was very impressed with this web-based PDF editor
Overall my experience has pretty very positive with PDFfiller.
My colleague recommended PDFfiler as I needed a quick way to sign documents while on the road. PDFfiller has all the features I need, even with the free version of the software.
I think to take this software to the next level, the developer should create browser plugins to sign documents without having to upload them to the PDFfiller website.
