Had a few difficulties with the process, but was able to sort it out after a little experimentation. I would like the ability to vary the size of signatures. I also tried to change the date format and set a new default but it didn't seem to work.
Overall, I was ok with the program but I really didn't find it fitted my purposes.

Wow! Finally a real online PDF editor, no more troubles on changing text and much more!
Just found it randomly, and since the beginning it shows me lots of features to edit pdf like texts, images, signs, highlights and more.
The graphic looks a bit oldie, but this is not a problem at all. Functionality first! 30 days trial, then you've to pay.

Excellent Product
The product is offering me the ability to execute contracts/agreements on the fly no matter where I am. When traveling and a signature is required for contract execution, time is critical to completing the deal. PDFiller allows me to do that.
PDFiller is simply the easiest and most useful product in its category. Simple to use and very user friendly.
Honestly, it has done everything I have needed to for the past 3 years. If I had to say something, I would say maybe an easier way to save and send. But, that would be pushing it.

I find that using your program is easy to navigate and looks professional when completed.
I find that using your program is rather easy to navigate. The only issue that I have had is when I try to print a document, there have been quite a few times that it will download to 63% and then gets stuck there. I have to close the document and try again....sometimes several times until I can print it. Besides that, it has been great!

The software was actually really great and extremely useful. I didnt really experience any difficulties with it and was exactly what I needed and a quick pinch without having to install anything. There was one small issue with my account, but the support team got back to me within the same hour and resolved what I needed. Amazing all the way through.
