What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
I know that most IRS forms are free and can be saved to my files, however sometimes trying to download the forms is difficult to do. PD Filler is much more user friendly and easy to follow.

overall it is fairly easy to use and it is clear, but it is not straight forward if you want to continue on with the next form, ie when finishing one form 1099 and you wish to do anothe

Great Product
This software has helped mainly with electronic signature creation but also with overall PDF edits.
The software offers a number of options for editing PDFs and is fairly user-friendly. It has an easy layout.
I do not like the fact that the software can lag when working with slightly larger documents. It can also be time-consuming to learn more advanced features.

Enjoyable and functional.
Ease of use, functionality, and security features. I like the automatic lock out for the encryption and I enjoy the accuracy in identifying areas that need to be filled out.
That I cannot move folders within folders under the encrypted area. I would like to be able to drag folders into other folders. I would also like to merge more than 5 documents at a time.

This is a great tool and is full of features that I really need for editing, exporting, merging and printing documents. I like all of the supported file formats and may use the routing features in the future. The pdfFiller will import huge .pdf files and allows you to save just one or two pages from that file for editing. It offers alot of flexibility and performance features which I appreciate for document management and workflow.

If you ever happen to chat with Support for a technical issue --- Hope you get Paul.
Paul worked with me for nearly and hour trying to figure out why my form got skewed.
I shared out my screen with him -- he diligently and carefully figured out the problem and got it fixed.
Saved the day!
Kudos to Paul!!

Though it is new to me
Though it is new to me, and signed up today, it will take sometime to know how good I am feeling about it. So far, I am satisfied Thanks

What do you like best?
The best thing is simply how it works. So many forms that need to be filled out and they are sent in formats that don't allow that. pdfFiller fixes that problem.
What do you dislike?
I haven't really found anything that I dislike. It's a great software.
What problems are you solving with the product? What benefits have you realized?
I do private consulting for government contractors and we have to finalize a LOT of Non-Disclosure Agreements. pdfFiller makes that a snap. Also we have many forms that have to be executed and it would be so difficult without this program.
