I wish it wasn't so expensive...I'm still on the free trial right now but this app is great. Maybe offer like a college student pricing? I know us kids in college cant pay $40 a month for it

So far it has been the go-too Application for filling out and converting PDF documents to word. It has helped me greatly in preparing forms for my job.

After searching for a long time for a tool that transfers pdf's into files that I could use on my MacBook Pro, I finally found one that works very well. I'm happy

pdfFiller has been amazing since I had to start working from home. It has allowed me to send in forms that I would normally have to print out write on and scan then email them back. This has cut down the middle man as well as saving me from getting a printer scanner and paper. It is time, cost and environmentally friendly.

Great Functionality, Amazing Customer Support, Great Experience Overall
This is a great platform, very seamless and user friendly. It does cost a bit so it would make sense if you use it quite often. More importantly, amazing support - the online chat response was quick (!!!), customer support staff was so friendly and understanding. Overall, such an amazing experience using this platform. Highly recommend you give it a go!

I needed to use the service for an application
I needed to use the service for an application! It was only needed once. The day I was going to cancel it due to no longer needing the service the money had already come out of my account. They immediately refunded it and even offered a discount if I wanted to continue using it. I highly recommend it was an easy to use service with many benefits packed in.
