What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
It was a life saver for me as I transitioned my insurance business. It looks so much more professional to import supplemental applications and forms and complete them with a keyboard. In the past, I did them by hand even though I worked for one of the largest insurance agencies in the country. In the past, I was unaware of your product, or I would have bought it myself to use.

I'm learning it slowly. You cannot merge files in the app on ios. I need that. There are also a few hic-ups. Sometimes after a signature the screen gets disoriented and you have to go back to documents list and reopen. Sometimes after reopening some of the modifications are gone and you must re-enter. Some of these issues may be due to not being connected to internet. Overall it has helped me go paperless and I'm getting faster at filling out my documents using it. A few tweeks and it will be awesome.

Nothing Particular other than finding out the particular IRS forms I expected to print from the IRS wasn't acceptable to download and print, and I had to purchase them when you advertise free IRS forms.

What do you like best?
The interface of PDFfiller is simple and intuitive. I think that most people can sign up and start using PDFfiller without having to spend much time figuring things out. Once we load a PDF into the system, there are straightforward menu items and labels that help to fill out virtually any form from start to finish. I can save to PDF format with my filled-in information or print right from the PDFfiller website.
What do you dislike?
Anytime I post my information online, I get apprehensive about how my data is being used. Though I'm sure PDFfiller probably takes measures to keep our uploaded and saved documents secure, I just never know with all the malware and server attacks that often occur, in general.
Recommendations to others considering the product:
Some people probably don't want to hassle with putting their documents through a digitized system, but I think once you upload one form to PDFfiller, you'll see how intuitive the entire process and may possibly not print out documents to fill them out anymore.
What problems are you solving with the product? What benefits have you realized?
My handwriting is basically terrible and I often get strains when writing since I typically haven't written by hand much over the past several years. PDFfiller lets me fill out PDF documents more effortlessly and lets me align text and other objects with great precision.

What problems are you solving with the product? What benefits have you realized?
I ended up not using there service but felt the need to write about my experience. I had a complex need that was nearly impossible to get. I signed up for a subscription and found out later my demand couldn’t be done. Their service team granted a refund quickly without the usual hoops to jump through. They were fast, professional and capable. I plan to use them for other projects.

Very easy to use, only thing is learning for a beginner is how to save the files so that they are editable in Microsoft word, and the work of art is not all over the place in the word document, thanks a lot! 10 stars for the service!
