What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
It's a good program, convenient, relatively easy UI. Needing to subscribe to a function that was free for a time on the Adobe software, is an irritating feature of life in the 21st century.

I liked the access to all the forms. It was great. And as I tried to do ever more complicated things with the forms (strikethroughs, initialing the corrections in random places, etc.) I learned more and more about the tools the platform has. It has just about everything you could imagine.

Loving the tool. It would be great if you could add an eye dropper feature so that if I alter text or numbers that are over a color background I can erase the copy fill in the area with the original background color and then revise the copy over the background fill

used a handful of other pdf programs, and while there have been a decent one here or there, most have been quite irresponsible, irresponsive, and irritable! pdfFiller is by far the most user-friendly, quick, and manageable one there is, notes this observer! am definitely glad i went for the platinum membership - has not only calmed my disdain towards pdfs, but i am actually having fun with them now! ^_^

Don't let the name fool you, it does so much more than allow editing
I use pdfFiller to sign agreements when I'm traveling and don't have the version of Acrobat where you can sign, on my computer. I actually like pdfFiller much better, because it allows me to edit things that Acrobat does not. I've utilized several of the templates that have been very well laid out.
I was pleasantly surprised to see all of the templates and formatting options that are built in to pdfFiller
There is really nothing not to like. I don't use some of the features, because we don't need them, but I can't say it's missing anything or has any issues.

Easy to find fast and proficient chat support
My issue is resolved in under 5 minutes.. I was able to speak with a live confidence human being in under 30 seconds.. I was charged for subscription that I forgot I had subscribed to and I no longer needed and the chat agent Kara had my problem resolved in no time. Locating this chat support option was easy and not hidden amongst FAQs or literature used to distract and deter you from reaching out

PDFfiller fills out pdf file with e-sign perfectly helpful!
PDFfiller is useful enough if you know how to use it properly. This is utilized in our company for signing in our timesheet and it helps me to become more productive. In just a second I can automatically attach my e-signature.
In our company, we need to electronically sign in our time sheet every week and PDFfiller is one of the most useful online softwares that our company is using that can be shared anytime and anywhere. Using this software, I can easily attached my e-signature and I can easily submit the required document needed to process my payroll. Sharing the pdf is as easy as including the email of the persons whom you want to share your file. Using this software, I became empowered in the sense that I can do multiple jobs simultaneously while I am on the go with my work.
If you are not familiar with how pdf works, it is hard to use the advanced functionalities of this software. As a new user, you need to spend time navigating the useful features of PDFfiller. I also encountered an issue in converting pdf to word-document format.
