I found that my typing was faster than the rate that the data shows up on the screen. I didn't like that. My attorney found this link for me, I was unaware that this was a system I would have to pay for. A customer service ticket was generated because I needed help.

At first I did have problems figuring out how to use it. I don't see a "copy/paste" button and wish there was one. Overall, as I start to use it more and more I am liking it. Regards.

Definitely Useful As I mentioned, it makes the mailing process much more efficient. PDFiller allows you to create and mail PDFs easily, saving you the hassle of getting an envelope, purchasing a stamp, maybe having to go to the post office, etc. For me that has been its greatest strength. The PDF customization interface isn't bad, but it's not immediately usable. It takes a little bit of time to learn how to use it effectively. Right off the bat: I would not recommend this software to someone who isn't tech savvy or doesn't want a bit of a learning curve, for example, employers I've had in their 50s, 60s, and 70s who don't really "get" technology. The interface is fine if you just want to sign a document, but is not particularly intuitive when it comes to doing simple things like outright deleting portions of text. Too many steps.

Convenient and easy tool! I've used pdfFiller since 2016. Easy to use, and has been great for converting, editing and merging documents and forms. I love that unlike programs like Adobe Acrobat I can access and use pdfFiller from anywhere. It has been convenient for work and home use. Had to convert and digitally sign legal documents from Word to PDF today and no one involved had any suitable programs, but I had the solution with pdfFiller!

customer support I had cancelled my subscription but it had not gone through and was charged. I explained this to the customer support team and they helped me very nicely and gave me a refund. It was efficient and very understanding!

I had an issue with accessing a form shared by a colleague. I wrote to the PDFfiller support team and received their response very swiftly. The instructions received via email were very clear and easy to follow. I was able to fix the issue within a very short time. I'm really impressed by the efficiency and quality of customer support.
