Just started using the program today. Easy so far. A little problem with the aligment of fields. It would have been great to use the "tab" key to toggle between fields.

I was sort of afraid to install and pay for this online. There is so much identity theft out there.. I was just a victim of fraud on my bank account. But this seem pretty secure and was easy to get going.

The experience before I purchased a license was not so good. The chat session I was on kept ending. The CSR said because I was not logged into an account was the reason. At that point, I was trying to determine if I even wanted to purchase PDFfiller or not so why would I need an account. I finally ended up purchasing the product.

Had to fill in a long medical form. PDFfiller makes it easy and a lot neater than my handwriting. Also, I have to fill this out once a year for the same doctor and it will save me time not having to fill it out from scratch. All I will need to do is verify any information to make sure it hasn't changed and place a new date on it and send it.

What do you like best?
Ability to use templates was the most helpful. I like PDF filler because I can encrypt and decrypt documents, merge PDF files, crop or rotate PDF pages. It's fairly easy to use but the interface isn't great.
What do you dislike?
The user interface is not intuitive for me. I liked all other features and don't have much bad to say. I'll continue to refer people.
Recommendations to others considering the product:
Great product!
What problems are you solving with the product? What benefits have you realized?
Filling out of legal documents for real estate transactions.

THIS THING IS A DREAM (although I did have some kind of issue opening up a file.) I used the MERGE function and it merged some files I didn't need. That was weird. So I'm editing one page at a time instead. That seems to be working.

Reasonable but not fantastic Pretty decent, I'm not sure it's the best PDF software available, but it's not bad and can complete most tasks you'd ask of it. The software works for the most part well and allows the signing and creation of forms, handy for mild administrative use. Support seems limited to live chat only, which is a bit of pain if something goes wrong. It could also do with a mobile app which I don't believe there is currently.

pdfFiller is very user friendly and is… pdfFiller is very user friendly and is very helpful to upload any document from my computer and edit, save and share it with anyone to review, make necessary corrections and sign it digitally. I am glad to find this product online while doing some search on internet and will continue using it during the free trial period before purchasing paid subscription!

Great customer experience with this company. Very responsive to technical questions and billing service cared more about our satisfaction than most companies even though it wasn't to their direct bottom line advantage. Will use them again surely.
