It is easy to work with. The best for adding content to PDF files whether it is words or photos. This is my #1 go to for files. I am in real estate and this is the best product
2016-09-24
So far works as advertised! professional version should include like a few business features to use like 10 times a week etc. That way I would give it 5 stars!
2017-05-08
Simple and versatile. Since it is new "technology" for me, I must use it with some guidance to understand all its utility, so the tutorials that are included will be handy without having to go to school to learn it.

What do you like best?
I am able to take a pdf file and change to a jpeg very easily. This allows me to change pdf file so it can be put on FaceBook. I also use it to make corrections instantly when it will take a day or two to get someone else to send it. I simply erase the incorrect data and type in the correct.
What do you dislike?
I have found that the program is not intuitive and there is a fairly large learning curve. I still don't know all the functionality, but what I know it will do make it worth it to me.
Recommendations to others considering the product:
Good program and a great price. Well worth it!!

I needed to create new documents when…
I needed to create new documents when my original templates had disappeared because I moved and my email locked me out. PDF Filler came to the rescue and made it possible for me to create all new documents and templates and I was back in business.

I found this site to be helpful, but . . .
I found this site to be helpful. A great time saver on changing documents. I would have saved more time, if I knew ahead of time, that the scanned in pdf, that I edited, would not be able to convert to a word document.

Free not so Free
Easy to use and alter forms to fit my needs. Was disappointed that it seemed to be free until you get to the end and you have to pay. Thankfully there was the option of the 30 day free trial.
