At first was a bit different in look and function but after a short time became very easy and logical to use. Still wish you could print directly from editing screen.

so far ease of use seams to be the direction this system is built on. I would love to see more controls to authorized users and an auto save feature from original templates after and before fill. over all I love how going paperless is very easy to use

I needed this program badly, just in the time for distance learning because of the Corona Virus. It was easy to navigate through and use. My only wish is that I would have found this program years earlier! I will update my rating to include the student (recipient) experience of pdfFiller after they return their first homework assignment.

Excellent Software and a great price Very good and have used it for years. PDF filler works so well and make it so easy to fill out forms online. It works and the price is very reasonable. I use this for all of my documents as it saves me time. I can't think of a negative with the software, it always works and has a range of features which are constantly getting better.

Amazing customer support I had to contact customer support because I, out of my own negligence, got charged for one of their products. They were extrememly helpful and resolved the issue, even though they had no reason to do so (except sympathy). Extremely nice customer support. Definitely recommend.

Fairly easy to navigate Fairly easy to navigate. Text does not always line up exactly right, but close enough to make the document readable. Overall, very pleased with the service.

I find it useful to put documents into PDF and or add to current PDF documents. I also find it helpful when I am helping my students and their class assignments for tutoring purposes.

Having to make the check boxes into… Having to make the check boxes into check marks instead of x takes while when you have twenty on the page. It would be nice if you could decide for the whole page.

I used this one time for squares for a fundraiser and was looking forward to continuing using this service needed for a side job; however, this side job fell through. I thought I had cancelled on March 2, but must have not submitted something. I was charged today. If I could be refunded I would really appreciate it.
