What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
Very good so far except that when I attempt to print completed documents the program changes the orientation of the doc so that it cannot be printed. I've managed a work around, but it's annoying.

It was hard to figure out how to get started, and I made some mistakes in the beginning. I saved two files too soon and now I don't know how to erase them because when I try it says if I delete it it will no longer be shared. Is it okay to delete it anyway?

I completed a passport application. The document was easy to fill & very professional in quality which made it very easy to be understood during processing.

It was a little tough figuring it out at first, but it seems to be doing exactly what I want it to do. In the sending and returning process, I think it could be done with perhaps fewer steps

Great customer service!
The site works very well and is easy to navigate, and when a miscommunication happened on my end the company was extremely polite, helpful, and quick in their response. Great customer service!

What do you like best?
PDF filler has allowed me to not only make forms being filled out easier but also allows me to keep them archived on their server so I had don't have to look for them.
What do you dislike?
I think the only downside I would say is the send to sign can be a little confusing. Some of my clients have had issues trying to sign things when I've used this feature.
What problems is the product solving and how is that benefiting you?
The only time I've had issues is when a form wouldn't load to the system. Customer service has always been great helping me out. They usually have the problem resolved quickly

It takes me a while to understand
It takes me a while to understand, I had my problems trying to understand the samples of where to find things, I did not know what a hub icon was,

Free trial
Edit: I appreciate the clarification and the time they took to reply to my initial review about the free trial. I will give it a go now and happy to leave it at 5 stars.
Cheers!
