What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
You have to carefully choose where to type, the format functions are limited and the printing is a little awkward as you cannot alter the margins. However, it is easy to use.

It was fairly easy to search out IRS forms but then you find out they're not usable because they're in Red!?! Also it said if you paid for a one-year subscription you save 65%, but the yearly cost was exactly the same as paying monthly and you didn't know this until you processed your payment???

I like everything about this program, but I prefer to be able to create folders without tags and be able to fill out forms without NEXT bars popping up all the time - they are annoying. But my overall experience with this program is great!

What do you like best?
Easy to use, anyone who I've sent a file has had no issues receiving and downloading. Some of them have told me they've gone on to use the product regularly themselves.
What do you dislike?
Nothing to do with pdffiller, but I sometimes forget to set up the files I'm uploading in the right folders. That's on me.
What problems are you solving with the product? What benefits have you realized?
Under the 'documents' tab, the 2 columns on the right could be made more distinctly different from each other to denote they are in fact different. They are just two shades of gray and not that different in tone.

Happy with the service
It has been easy to use
I like that is allows me to edit PDF's - and that all of my colleagues can log in and use the same services from their computers.
I find it takes too long to save and open documents

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.
