pdfFiller scores top ratings on review platforms
I love the site, I don't like all of the pop ups though! I constantly have to click out of the pop ups when opening a new form. That is my only complaint! But, all in all, I love this site and it helps me be more efficient.
I changed my review because of excellent customer service. I had issues with the product that made the program unusable for me and was not happy with the cost. A representative contacted me right away and refunded my money before I could even ask. For that, I am truly appreciative and wish more companies would follow their example.
So far it has been frustrating ( just because I am not tech savvy) I am just trying to reprint a pay stub that I have lost from a former employer and I just keep running into problems. However after watching a video I figured it out without a problem. Customer service is A1.
I am a Special Education teacher, and to be able to take pdf files general education teachers are using and enter in text boxes so my students can type into the pdf is very helpful for my writing challenged students. I can also fill in answers to study guides and email or send home a paper copy for my students to study from also.
It keeps mixing up my two accounts - - one subscription with an aol email address and one free account with my fire dept. address. I believe it's due to my MSOffice password settings.
Can be a simple way to fill out documents.
I can fill out a document pretty fast. Its functions are easy to understand. Overall it is easy and anyone can use it even if they are not tech savvy.
I don't like how I can't control the fonts and the font size. It automatically selects the font size and sometimes it can not be changed.
Love, Love, Love the PDF Filler
I recommend this product.
This program makes it so easy to fill out any PDF. It really helps in our office for everything to appear highly professional.
It is taking me awhile to learn this software, but I think that once I master it that it will be very helpful in our office.
My experience was excellent. As a first time user, the program was full featured and easy to use.
Ability to complete my tasks quickly and easily.
Ease of use. The program was very intuitive for me to use from the start and had all the features I needed to complete a complex form. It is an excellent piece of software.
It was actually nice, easy and convenient to use. It is just that I find it expensive so I revert back to my old ways means manually filing or writing in forms. :)
