Everything has worked great and while I honestly don't know what there are companies that still use Fax, they do exist and I need to work with them. Love PDFfiller and everything it provides.

It was very helpful to have forms at my fingertips that required little effort to complete. It also provided some forms that I did not have but a customer required. Very helpful!

Great service! Could use some updates though. The site is rather slow at times, and when changes text size there seems to be a bug where the page needs to refresh or reload. Also, general improvements on loading time would be nice. Also, please make the process of saving to PDF less steps and less clunky. I don't need to be shown where the pdf will be once downloaded.

I find this really easy to use. We are travelling full-time so haven't got a printer. This saves us searching for a Library or private printer to use.

This is an awesome program
This is an awesome program. I've searched for a long time and haven't been satisfied with what was available on the internet. This is a program that does what it says it can do and does it very well... finally!

Trial Offer
We were reviewing this application and thought we had agreed to the trial offer. Actually, we didn't want the trial offer. When sending an email to their support team, they immediately responded and took care of our request, no questions asked.

Even though I didn’t use their website
Even though I didn’t use their website, I am very satisfied with the customer service. I have subscribed and forgot about it and it took the money from my account. I contacted customer support and my issue was solved in less than a minute! If anyone has the same problem, don’t worry, just contact them and they’ll help! :)

I love that pdfFiller.com has a vast selection to search through, although it can be frustrating to find what you are looking for because even when you change the search information, the same ones pull right back up. The price is fair if you use it daily or at least 3 times a week, which I don't but I use it frequently enough since there is no cheaper option than the monthly rate.
