What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
I did not like the fact that when you decided to make it a service that charges you money, there was no warning. It forced you to pay if you wanted to keep your documents. I'm past that now and I am really ENJOYING it now that I am a paying customer.

Excellent Software and a great price Very good and have used it for years. PDF filler works so well and make it so easy to fill out forms online. It works and the price is very reasonable. I use this for all of my documents as it saves me time. I can't think of a negative with the software, it always works and has a range of features which are constantly getting better.

pdfFiller.com gave me faith in online… pdfFiller.com gave me faith in online companies. I have no idea what I was trying to accomplish, but had signed up for a 30 day trial. I never used the program, just must have been sleep working. Anyhow, I was so surprised when I got the notification that I had just bought a year subscription. I was beating myself up and trying to figure out how I could be so unaware. I first tried to call. The phone was endlessly busy, I thought wow I just lost $122 (I paid in Canadian funds). Anyhow, I thought I may as well try sending an email. I could not believe it!!!! The response was almost immediate. Max, took care of everything. He issued a refund, and let me know he had cancelled any future subscription. I was in absolute shock. If I had a need for pdfFiller, in that moment, I would have signed up for years. THANK YOU for being accommodating and obviously trustworthy. Again, you have given me a bit of hope for humanity.

pdfFiller is user-friendly and the site is easy to navigate. I love the fact that a function stays the same until you change it, eg. a font size and format. However, I would like the option to use all the Fonts that I have installed on my own computer. When a page is duplicated, I'd love it if the 'changes' made to the original using pdfFiller, could also be duplicated rather than simply a duplication of the original document. I also can't seem to find a way to cut and paste text to apply it in a different area of the document, which means that the process of replicating a change is more time-consuming, but this could be my current unfamiliarity with the software. I was impressed that within a couple of hours of use, I was offered the option to attend a webinar to improve my understanding.
