Awesome, Love it. It is a good thing because I just didn't know they would charge me 9.00 dollars a month all at one time for the whole year upfront... Thanks for the heads up guys.

I love the program, would be easier to fill dates on my form if I could type the date without the scrolling box. I also wish it was a smoother flow to save/print and back.

Amazing Customer Service
While I was reviewing a couple of unauthorized charges on my PayPal account I noticed they were from PDF filler. Upon further investigation as to what PDF filler is, I realized that this was due to something a professor from a course I had taken last year had required the class to use to complete an assignment. He assured us that though we may need to put in our personal information, the service we were using would be "free". I did not realize that “free” was then turned into a renewable purchase fee. I contacted PDF filler to dispute the charges and explained what had happened. This company responded to my email with genuine kindness within a couple of hours to assist me with providing a refund upon receipt of a response providing verification information. I emailed them the information and again, within a couple of hours, I received a response that I had been refunded the fee. I appreciate how professional, considerate, and amazingly responsive this company has been- the whole process was quick and painless and I will certainly consider using PDF Filler in the future should I need such a service!!

Amazing easy and reliable
Intuitive and logical to use. Makes my life 10x easier when sending documents. As a doctor I am constantly sending documents and anything to make this easier is worth it.
The time for loading and processing. A little cluttered and busy the interface. It would better if it were free.

Ralph - My favorite support friend
I requested a refund for a yearly subscription that I did not remember signing up for. I reached out once before and did not receive a response. I reached out again today (2020-10-24) and Ralph responded right away. He was extremely helpful and nice and solved my problem right away. I am extremely satisfied with my experience and I will definitely keep PDF Filler in mind if I or my friends need a safe place to store or edit documents. Thank you for your great support and for hiring a great employee like Ralph! He is amazing and I truly appreciate him.
