I worked fine for my needs of filling in a PDF file and saving it with data. I would like to see the ability to CREATE a fillable PDF file that I could distribute to others to fill out, save, and return to me.

It has been good, but the saving of the files is not that easy, have to upload document every time you want a new copy.
The easiness to write pdf's and print them out.
The documents are not categorized and it would make it easier to find.

At the first, i had some problems with using the application but later on, I learned how to use it, still, I need further study to be more familiar with it

Finally a one stop shop to do everything you need to do with PDF's! It's never been easier to sign documents and move them down the chain of command!
The learning curve is something we're still have trouble with.

I activated to try for the first time and only needed for a single transaction. Very easy to use and should I need a service in the future, would definitely purchase.

I signed up originally to utilise this service. Whilst I did not wish to continue with the service (just wouldnt need it again) I did struggle to cancel the service. I sent an email outlining my issue and got the quickest response back and my account fixed and funds returned. Great service if you do require all the time. Easy to use. Highly recommend.

When I realized I had to solve a problem involving this company, I prepared myself for a multi-day, inconvenient annoyance. Instead, I was very pleasantly surprised to find a prompt reply which ended swiftly in a satisfactory way ... even though it turned out to be my own fault! I used the program for only one item but I "poked around" in it to get a better handle on it. For anyone using PDF's on an almost daily basis, I'm sure pdfFiller would be an extremely useful tool.
2020-04-21
I would only add that when adding text to the editor, it can be moved without blocking the height. Sometimes the PDF blocks the location of the text and it is difficult to align it with the original text.
2025-05-20
It works!
The application is relatively intuitive to use. It was the only one that offered the full PDF fillable experience under a free trial to really test it. I recommend this program over others I have tried.
