Great product. Have been using it for years. Not easy or intuitive to renew subscription. Ended up getting a 50% renewal but was initially offered a 75% renewal. Mainly use this for personal and light business use.

I was looking for this solution. I work from multiple locations and multiple computers and using other pdf softwares that only allowed me to use the software on a certain number of registered devices was not a good solution for me anymore. I would have given this 5 stars, but I am still learning to use it, and I wish it was faster. In all fairness, the the lags may have to do with the processor in the chromebook I am primarily using it on right now which may not be that fast. It was an inexpensive device so it is very possible that my device is the reason for the slow transitions and not the software.

What do you like best?
I like the accessibility of the application. I can access from anywhere by just using my browser.
What do you dislike?
Sometimes the sizing is a bit tricky and I need to play around with the edits to make it work.
What problems are you solving with the product? What benefits have you realized?
I am able to take pdf documents, to which I have lost or never had the source file, and easily change them to what I need. Also, another great use is to fill-in forms in forms to which i only have hardcopy.

Does it all The best program to work with documents Easily completes and adds information to any document or report. You can size the information to fit the provided space, cut and paste and maneuver easily within the document. You can access the program and the documents you have completed as the application is on the web and it retains your completed report in their system. If they could combine other pdf tools would be awesome. Some of the more common pdf functions include moving pages, separating pages and duplicating pages, etc...

Excellent support and customer service I registered for an annual membership, but I didn't pay attention that the membership fee is calculated in US dollars. I live in ****** and it was expensive for me. I emailed support department to cancel my membership and they responded in less than an hour and sent me a full refund.I appreciate the excellent customer service and proper support, polite and professional behavior of the staff.

It was wonderful to use so I didn't… It was wonderful to use so I didn't have to go to town to fill out the particular paperwork i needed to turn in. The only negative was I thought I was in a 30-day free trial period, and I was charged two separate charges, though they were very small, but yet I was charged.

Daniel I was disappointed to find that PDF filler had automatically charged me for a subscription I did not agree to. I felt very stressed when I saw the sum of money that had left my account this morning. I contacted the helpline via the chat service they offer on their website and I spoke to daniel. He was extremely efficient in his help and immediately refunded my payment and canceled my subscription. I would like to leave a 5 star review for the customer service I received despite my initial disappointment in PDF filler.
