I love the convenience of sending a fax from anywhere I have a wifi connection. The ease of filling PDF documents is great compared with other programs.

I use it for filling out work related forms. The forms look much better when filled out online rather than writing in all of the data. I'm able to save a copy online or on my computer, rather than filing a hard copy. It's very convenient and the forms look good too.

It is a little hard to learn and it is a little expensive, but it is the best "filler" program I have ever used and I am glad and grateful to have it.

I needed to create new documents when my original templates had disappeared because I moved and my email locked me out. PDF Filler came to the rescue and made it possible for me to create all new documents and templates and I was back in business.

Still trying to utilize and familiarize with the app, however with my first use of the app, it should be an app that every body should subscribe to because it has more in it than expected.

Student charged 115€ despite cancelling free trial – very disappointed
I am extremely disappointed with my experience on pdffiller. I had signed up for the free trial, made sure to cancel it before the end, and yet I was still charged €115.20 for a full annual subscription without my consent.
I am a student, and this unexpected charge has pushed my bank account into overdraft, causing me financial stress. I never agreed to any paid subscription, and when I log into my account, it still shows as “free”, proving that I had cancelled on time.
After checking Trustpilot, I realized that many other customers are facing the exact same issue — this seems to be a recurring problem.
I have contacted customer support and sincerely hope they will resolve this quickly and refund me. But this situation is really unfair and unacceptable.

Very good service
Very good service. I used it once to fix my resume and forgot to cancel. Accidentally subscribed for an annual subscription so was shocked to see $321 come out of my account. That was all the money I had. I got in touch with the customer support team and they refunded the money and cancelled my subscription immediately. 10* customer service - love you PDFFiller!
