What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
Hard to find the erase button. But after I asked, I found it buried in the "tools" --seems like it should be more visible. Love the tool's simplicity otherwise.

Generally very good. When you print it saves first which I don't want it to do and "Save As" does not allow you to rename which is not right. Other than that, it does what you want.

kind of difficult to understand..sometimes it would not fill out the form and sometimes it would, then go back to the first signature and had to keep confirming.

I found PDF filler to be very helpful, however there was a bit of confusion with the cost of the account account. I I thought that I would be getting charged $6 dollars per month however my bank account was charged $72 dollars for an entire years subscription. I do not fill out enough documents to make a years subscription worthwhile. If that is the case, I think the website should give you the option of a 30 day trial period, and then give you the option of committing to a 1 year subscription. Otherwise, be more clear that you all are charging the entire $72 as oppose to the $6 per month. I have since canceled my subscription and I do not intend to use the website any longer. I would definitely like a refund effective immediately.

I felt very mislead, I entered a lot of info onto a form and was only told when I tried to print there was a charge. There was a monthly charge shown but when I selected the monthly option the cost suddenly shot up
2017-04-08
I like it but only need to fill in a few forms a year so it's not cost efficient for me. I would pay if the pricing were different. Instead I'll just unsubscribe.

The one time I used helped they…
The one time I used helped they actually helped. The other service I tried to use before this one, I couldn't get any help.

The PDF filler application and the great tool list
The PDF filler application and the service from customer service and billing were all really good. The application is very helpful in this format for small business needs. Would recommend.

This app is not flooded with ads and/or private tools as far as I could check
I just needed to merge stuff and this website (didn't know it, it just popped after a simple search) showed me tutorials for all the tools they have to make my documents complete and personalized as needed. I am here because we live in an era where an app that does not flood you with advertisement and charge your for each tool available calling some of them 'premium' or 'plus' or 'pro max' is RARE. I want to be explicitly thankful about this. Useful for the purpose of being useful. Didn't believe stuff like this existed anymore.
