I am just learning about this program. So far it is easy and appears secure. I have initially been using the redaction/ blackout feature for several PDF files that I am sending to a client and it has been very effective. I am impressed with the "save" feature in that it allows you to save the edited file in a different format, I.e. Word.

I like it but only need to fill in a few forms a year so it's not cost efficient for me. I would pay if the pricing were different. Instead I'll just unsubscribe.

This is by far the best I have tried; awesome features, well designed and intuitive as can be. Deeply regret I cannot afford to buy it; I run a very new, very poor legal aid society with 0.00 left in our budget for such things. Recommended highly.

Quality solution to alter PDFs to be tailored to suit a particular presentation to a client

Top quality all round Only used the free trial for a specific task needed at the time and pdfFiller offered everything I asked for, unlike other services I tried. Very straightforward and accessible. Fast forward a month and I’ve forgot to unsubscribe. I see an email saying $180 dollars has been paid out. Of course, it was agreed upon, the yearly subscription follows the free trial. But I didn’t want the subscription, I hadn’t used it since the first day. And to be clear it was not for a lack of quality but rather a lack of necessity. But all I had to do was email the support team and even on a Sunday their responses were immediate, clear and thoughtful. I explained the situation, they saw my predicament and even though I was at fault, they did not hesitate to cancel my subscription and repay me in full. The money was back in my account just hours later. Superbly run business!!
