What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
Basically a good PDF editor, the one failing is that formatting is not preserved during cut and paste. Could not get the correct formatting with the tools in PDFfiller.

very intuituve. quick and easy to learn. i operate mobily so i like the fact that i can use it on any of my 4 computers any where in the world. Very easy to drop text in. I like the erase and highlight feature. I tried at least 6 other platfroms and they were too dificult to use.

I just wanted to fill one document but I don't have full adobe on this machine. Then I wanted to print and I had to buy it to print which was okay as I need a system. It works great now that I am learning how it flows.

the biggest difficulty I have is when I am trying to re-order documents (move them left or right) -- it is just very difficult to see them. I wish the functionality allowed for enlarging the docs so that I could see what it is.

Just started using it today
Just started using it today. I'm afraid it will only let me save 5 documents to my computer because I got a pop-up about that

Overall, this product is good and I would recommend it to a friend. Like it over Adobe.
When I played around with the trial, I liked how you had many options and the program layout was nice. Love the ease of use when trying to alter a pdf.
I wish I had a longer trial period and sometimes I could not save a file causing me to save over the original file.

One time using pdfFiller the first time…
One time using pdfFiller the first time saved me time doing a very basic operation (checking off fields when I was entering information from forms into another program). I have used the other program for over 15 years but recently moved from a PC to MacBook Pro. The program for Mac is harder to use than the PC product. I have spent too much time and frustration with that program. After one use, I had to spend much less time with little frustration. I hope it continues as I using pdfFiller
