What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
Liking it so far. But when I'm using the eraser, line, or other tool, it automatically changes back to text add mode after saving the change I've made rather than staying with the eraser, line drawer, etc. If you did it this way b/c more users keep erasing, adding lines, highlights, etc when they intend to make only one change and start typing then nevermind. I would rather it stay with the eraser, highlighter, etc. and I'll switch back to adding text when I'm ready to do so. Hope that helps.

It took me a few minutes to figure out how to find you and to find the form I needed. But had no trouble after figuring out the ins and outs of what I needed to do. Thanks

I've had problems expanding boxes to fit text in. Customer support sent a YouTube video and that was some help and fixed one box, but then I had problems with a second box and just didn't have the time to keep trying to fix the problem.
After a few attempts I was able to fix the problem, and now I am very impressed with the program.

What do you like best?
I like that the program is pretty intuitive and that I’m able to figure most things out on my own. I am able to erase and utilize previously filled forms that otherwise I might have to obtain from another source. The time and energy savings for me offsets the cost. In addition, I like being able to work on the program from a mobile standpoint - as long as I have cell phone or internet connectivity, I’m able to access and work on documents at my convenience.
What do you dislike?
Nothing that I really dislike. I still struggle with how to send a document directly out of the program to someone that may or may not have sufficiently updated software or skills to open. I’ve worked around this by saving the document and then sending from a cloud storage site.
Recommendations to others considering the product:
I’ve used tillable Adobe programs and PDFfiller meets or exceeds the capabilities of the Adobe programs I have used.
What problems are you solving with the product? What benefits have you realized?
Ability to fill out insurance applications and forms for use with multiple end users.

Lifesaver!!
Lifesaver!!! I am not always able to print documents, fill, them out, sign them, and then scan them in and email them to recipients. This program allows me to skip most of the steps.

Worth the money
I've been subscribing to this service for several years! I love it! It's nice to be able to start on my laptop or phone and pick up where I left off on the other device. The download notification feature is nice because it ensures the person got your email and actually downloaded the file. Will maintain my subscription for the immediate future.

Logging issue troubleshoot
I was having issue logging into pdfFiller with the password that I remember, at the same time could not receive any email to reset my password. Harmhon, the live chat agent from pdfFiller, has patiently understand my situation. Although most of the time is user's issue that they don't check on junk mail or they have some instruction/rules listed in their setting. But Harmhon is able to figure that my email address was actually not being whitelisted in your company whitelist. That being said, after Harmhon inserted me into the whitelist, i am able to login without any issue again. I really appreciate Harmhon's patient and service. He is definitely a precious asset to pdfFiller! Keep up the good work!

Excellent customer service -- quick response time and great problem-solving ability. I found the PDFFiller app itself to be a little cumbersome to use. I'd hoped it would allow me to do what ***** does but for less money, but it was more like *********
