What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
After I downloaded the program, I realized the price was going to be $19.99 a month. That seems pretty pricey. I am going to speak with finance and see what converter I can purchase. I am impressed with your application and customer service and will keep it in mind when making a decision.

It is very good for the most part; however, the pop-ups are very distracting. Also, when filling up a table with numbers, is is hard to line them up.

The only reason my rating isn't a perfect 5 Stars is regarding getting an a document notarized online. Your website says it will be at no cost. But when linked to the vendor notary person, she said the cost is $25. When I contacted your company a couple of times, it was indicated someone would get back to me w/ answer. But that never happened.

This application solved my work!
I am constantly receiving email with PDF attachments which I must review immediately and in many cases merit that I fill or edit them, for which I had to download the mail file and manipulate it to send it again. Well that I finish since discovering this extension for my mail, through it I open and edit online from my mail the file received. This speeds up the tasks.
The only thing I should mention is that being an online job, the Internet connection must be constant and efficient so that the work flows quickly.

my son is in the military. so I needed some information notarized. with me and him being in different locations. I was able to use the pdf filler to sign my name. then add my son to the document as a team. so he can sign the document as well. after both signatures were on the document. and notarized by PDF filler. my son was able to get the document notarized by a notary.

It's diffcult to make some changes or fix mistakes. I have notice that it is had to find a blank form. So if you need to file say 2 941 forms. I couldn't just choose another 941 form from menu. I had to use one of my saved forms or let the site and choose to file 941 and log back in

I had trouble logging in to my account
I had trouble logging in to my account. It was a small issue but I sent a text message and got a reply soon after. The Customer Service at pdffiller is very responsive. I have been a customer (for creating insurance forms for my medical practice) for three years and it is an excellent service. It is user-friendly and intuitive and simple to use. I highly recommend pdffiller.

Combining two files was relatively easy once I read the How to Guide three times to figure it out. But editing text in the file resulted in a change in the font that was not particularly satisfying and could not be corrected.
