Works great, nice little addition would be the ability to copy sections of already input text and drop more copies of that same text on other parts of the page. Would make what I do ALOT easier.

PDF Filler is intuitive to use (easy buttons). The one add I would like is to be able to edit signed documents and initial the edits...currently signed documents are Read Only even to the originator.
Robert R
I love PDF filler overall. It is a little cumbersome for my purposes because I'm printing out documents for patients while they are seated in front of me. The pages take time to load. Maybe that is my computer. I have to click several times to get to the final print link. But, I like the ease of editing documents.

the experience was mostly good, however, when coming from a google doc and putting the document here to convert into a pdf, the drop down tabs that were originally in the google doc did not work- in that way, it was tedious.
Anonymous Customer
An invaluable resource for filling out forms. Incredibly fast customer service that is exceptional in handling your needs. In this day and age when companies can treat you like a number, it is nice to know that PDF Filler is not one of them. They treat their customers with respect and attention, satisfying their needs quickly and efficiently. More companies could learn from them on how to conduct business.
