It's a great program, but it can be a bit glitch-y when trying to fill in information. A minor problem, but it does get in the way of having an optimal user experience

I like PDF filler for quick fill in of forms. One thing that isn't great is that it won't load certain docs that have had electronic signatures - I know it is to protect that doc but sometimes its a pain.

it is very easy to use, it has very clear tool box, however i haven't used it for very long. but this far i am completely satisfied. but i will always give 1 star left because i know there is always a room for improvisation

Took me a minute to get the hang of it... after that no problem. Not sure if there is a tutorial for typing in text and moving the text where you need it...

I found this site to be helpful, but . . .
I found this site to be helpful. A great time saver on changing documents. I would have saved more time, if I knew ahead of time, that the scanned in pdf, that I edited, would not be able to convert to a word document.

Great app!!
I like this app very much it makes keeping track of my medications, allergies, surgeries and other medical information easier and all in one place. I can just print what I need to take with me when I am going to see a new doctor for the first time. I recommend this product.

Ralph - My favorite support friend
I requested a refund for a yearly subscription that I did not remember signing up for. I reached out once before and did not receive a response. I reached out again today (2020-10-24) and Ralph responded right away. He was extremely helpful and nice and solved my problem right away. I am extremely satisfied with my experience and I will definitely keep PDF Filler in mind if I or my friends need a safe place to store or edit documents. Thank you for your great support and for hiring a great employee like Ralph! He is amazing and I truly appreciate him.
