What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
I love it, it's more user friendly and reasonable than Adobe filler and keeps changes, doesn't always work that way with Adobe. The only thing is it needs alignment buttons, like center, left or right justified. Setting up new forms requires much counting spaces to center. Other than that am happy thus far with the program.

I love this tool
I love this tool. I shared it with my mom who still has to fax things and I did not want her leaving her home to fax at other businesses. I think a video on how to create more fillable boxes would be helpful. Although I figured it out, it took me about 30 minutes. I can imagine for even less tech savvy people it could take longer.

Great and simple pdf editor
Easily edit, share and secure pdf documents.
This is a basic pdf editor that does everything I need. You can edit by adding text, making notes, make tables, add a signature area, etc. It is also very secure and easy to share and collaborate. Even the free version is awesome.
It's not the fanciest, smoothest software but it gets the job done. I would like to see the interface beautified a bit.

Very easy to use
I like that it notifies me when someone has completed the document. I also like how you can customize the fields between numbers and dates which makes it fool proof. Support is very quick to respond and helpful.
I have been trying to set up a document to copy certain fields throughout so they do have to enter their "name" every time, but I have had trouble trying to figure it out.
2017-11-27
the features are good, but the interfaces are a bit clunky.
For example creating document sub folders wasn't as intuitive as other applications. Additionally there are some documents I would like to move to Trash, but once it been sent out for E-sign it appears it can't be trashed, so I had to move them to a folder.

What do you like best?

What do you dislike?
The recent changes to the interface. I'm struggling to find the buttons I always used.
What problems is the product solving and how is that benefiting you?
Changing information on PDF proposals and helping create timesheet reports

I needed a straightforward way to file…
I needed a straightforward way to file an extra tax form, and PDF Filler helped me out! Much easier than finding the form on the IRS website (somehow impossible?) and hoping for the best.
