What our customers say about pdfFiller

The only reason I did not give it 5 stars is because it does not have an option to undo things if you make an error. If you make an error you have to restart the whole thing. Otherwise, its a great program to have!!!

Great experience for me since I'm preparing from a remote location in the mountains using the e-signature feature sending to legal services for filing.

This app made my work easy
This app made my work easy, changing pdf documents onto ppt to present the document in front of my class on the projector, it works perfectly!!

I am very impressed with PDF filler and its features. i am not the most computer literate person and i do have a bit of trouble navigating around the program so a demo of some kind would help me a lot if there is one that i can watch. I guess its just a case of playing around with it but there's probably loads of easy shortcuts that i could use if i knew about them .

The software worked great but didn’t…
The software worked great but didn’t quite fit my needs as a student who uses pdf editing 90% of the time to write with a stylus for exams. The reason I gave them 5 stars is for customer service. They were very kind and helpful when I contacted them about my account.

Nice product and Cust Service
Thank you for the quick refund..i was using the trial version and the product is excellent and Cust Service is very quick

I really like the service a lot. It is user friendly and intuitive. I like that this also comes with Sign Now so that I can have all the forms I need for my business easy and accessible for me to get electronically signed.
I would give it 5 starts except in the Sign Now program the program should default to the text box for people to sign and then have the live signature be on a separate tab, so basically reverse what it is now. It is hard for some people to get to the text box for them to type their signature.
I use this all the time in my business and I would recommend it.
2020-10-18
Best part of the service is responsiveness to online support, but there are a few minor glitches that should be addressed. I'll elaborate later when time allows for it.

A good program (and nice people)
A good program, a bit too comprehensive for me (in some ways), and a few (to me) important features were missing.
After my trial period, I was accidentally invoiced for a full year, the support department solved that nicely.
