This program has allowed us to reduce the amount of time it was taking to complete our main work task by at least 50%. The only significant improvement that would increase our experience would be the ability to rotate any specific text input by 90 degrees.

I am glad to have this service available. The use is a little awkward ... hard to navigate between pages. Wish it was easier. I do like the ease of accessing and saving documents from the website to my computer.

AMAZING CUSTOMER SERVICE
I was charged a subscription fee and I didn't understand why, so I contacted the company via chat. The agent that assisted me was amazing!! She totally understood and was very helpful. She was extremely professional. I really expected that this was going to be a very unpleasant experience for me, but it was absolutely pleasant and positive! Thank you! I would give many more stars if I could.

I accidentally forgot to cancel my subscription (I only wanted to use the free trial) and my PayPal was charged $144. I freaked out and emailed pdfFiller’s customer support and they got back to me within an hour and refunded me! In the future I plan on using their services (right now I can’t afford it) because of how amazing their customer support is!
