I discovered PDFfiller.com during a Google search. I wanted to fill in a job application professionally instead of hand written. How very nice of them to let me try it for free. I've tried other free services in this same manner and they were just too difficult to work with when I'm in a hurry. With this program, I clicked on the application, it downloaded, and I started filling in my info! No learning curve AT ALL.

This is a great app, I just can't afford it right now, that's all. It's well worth the investment if you can afford it though! Trust and believe that! They will give you a free trial period. So, try it and you will see! It really is a great PDF app!

I am very happy with the services of pdfFiller.com
Their customer service is excellent. A payment was automatically made from my credit card. However, after talking to the customer service, I got my refund which I never thought would be possible.

Great features. Easy to learn.
The features I've used so far have been fantastic. pdfFiller is quick and easy to learn. The only feature it doesn't have that I would utilise is when creating a form and using the 'formula' option I'd like to be able to add formulas like in excel e.g. =field_1 so that I can duplicate a form entry where it has been entered previously. I chatted with the live support team about this and they were fast to respond & took this request onboard for future updates. A great product and fantastic customer service.

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.
