What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
I was in a jam! Law School needed me to fill out three documents and sign them and return. The only problem was that I did't have a fax, or scanner. With PDF filler I accomplished my mission at a fraction of the time and cost.

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.

Stress free
I am able to get many projects done quicker and more efficiently with the use of PDFfiller. I enjoy the benefit of multiple different ways to finalize the project, send for signatures, print, email, save, etc.
I love that this software is simple to use and I don't feel I need training to use it. Almost all the functions this software has is what I need to complete task in my professional role.
I wish there were ways to combine documents, or if there is, making it easier to do so.

All trials have been very satisfactory. It has been easy to learn the use of the various features. Especially the relatively small size of the ready documents is appreciated.

Great software program
Great software program, lots of useful and dynamic features, good trial offer - better than all comp., fairly user friendly interface given some basic computer skills, etc. There are a few limitations or features that if were avail., I would increase my rating to 5 instead of 4. Thank you..

So easy and convenient to download and complete. My only issue is I wish with the forms you can scroll down to sections without having to tab each field or using you mouse to click in a different section.

I would like more font options. Other then that I have no problems
Recommendations to others considering the product:
pdFiller will make life a lot easier dealing with forms and getting signatures
What problems are you solving with the product? What benefits have you realized?
Many times we need to make forms our own such as adding our logo. So we don't have to recreate the form or document.

The experience is great because there have been some documents that I needed to change, but for the free trial I wasn't expected to get charged at all. It's free for a reason. That's all apart from that, it's a great tool to have.
