PDFfiller makes work easier.
Easily fill out forms online that don't provide you that ability.
The program is very easy to use. Glad I have it.
None, really. If there's any errors, it's probably from me, the user.

I love the PDFfiller, I find it very easy to use.
It is making my newsletter each month alot easier to create.
I am able to erase words that I don't need & put in the ones that are easier to read.
I have some PDF's that are very light gray print and don't copy very well. I can take out the words that are too light & replace them with clearer, larger, darker letters.
It is easy to go back to change anything that is not what I want.

I needed to send a corporate dissolution document to the state of Deleware and thanks to pdffiller, I was able to find the document I need, fill it in online, and even was able to mail it USPS through the site without ever having to print out a document, manually sign it and have to go to the post office to send it registered mail.

It is difficult to find the exact years form. For instance, I searched for 2019 1040 SE and I got a lot of 2014 forms. I had to over search for the correct form.

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.
