AWESOME program but too expensive
AWESOME program, but the monthly cost is WAY too high. Should charge customers a more affordable price of $10/month. And stop trying to force us to pay for a whole year up front -- what if I don't need it for an entire year? Fantastic features, easy to learn, a pleasure to use. Just TOO EXPENSIVE.

Gets the job done!
Amazing, all sorts of adjustments can be made (Text, highlight, signature, templates etc). User friendly and a simple enough design. Cheaper too! My only issue is internet connection, perhaps if it was available offline (I'm not sure if that's a feature or not), it would honestly replace Adobe Acrobat all together.

Great product and full refund when cancelled before trial ended
I took out the trial and paid 2 x €1.25 installments.
I used the product which was the best I found especially given you can edit PDFs with it.
I cancelled after a few hours and both payments were refunded as promised.
I would have been happy to pay a single use fee for this service but the subscription is too much for my once off use case

Phenomenal Customer Service
Due to the pandemic, like a lot of people I was forced to work from home. My employer doesn't adequately support us in this task and so one day as a matter of urgency I started the free pdfFiller trial for a month. I set a reminder to cancel my subscription but I didn't complete the cancellation. When the annual subscription fee was taken from my bank account I was devastated, it's a deduction I couldn't afford and my employer would not reimburse me. The team at pdfFiller were amazing. They ensured I successfully cancelled the subscription and they also processed a refund. The speed of response was phenomenal, their empathy towards someone who genuinely could not afford the subscription was so appreciated. Their customer service is like nothing I have experienced before. Keep up the great work.

Excellent application but not sure if…
Excellent application but not sure if its worth $9 a month for an individual user working on domestic household forms. Definitely worth it if using for a small business.

So far this program is a game changer
So far this program is a game changer. I wish it was cheaper (a discount for teachers on a year subscription would be wonderful!) but I like what I am seeing so far ;)
