I was sold on the ability to edit anything on the document easily with PDF filler. I have the latest copy of Nuance Power PDF Standard that I used to create an editable form and I could not figure out how to edit some of the fields on the PDF doc. (I believe the source PDF file may have been poorly designed for computer input.) Anyway, I find PDF filler very easy to use--no need to convert the document to a form--just start editing with the various tools. Neat!

I am not very savvy with computers and am trying to learn more everyday. Your system was easy enough where I did not have to call my kids to help me figure it out. Thank you for the simplicity of the web site. It is helping me meet my needs and not be frustrated at the same time. Great feeling to be able to use this web site and get what I need from it. Thanks.

easy to use but i don't use so much its really a good app, but at the same time it does not fix all my needs, but i usually do need the app when i have to edit some pdf file, because i feel its easy to use, very intuitive, but i don't use so much the signature features should be improved

Absolute gold in my role in sales Absolute gold in my role in sales - to condense a complex sales proposal into key points with notes, comments and sticky notes...it's been a massive help to my business.

Glad to have it Glad to have it. Wished i didn't have to reset with every entry. It should assume you want the same font until you tell the program to change. Gets tedious to change for every number on the page.

Great Tool & Responsive Customer Support I've been using pdfFiller for several years now, and find it easy to use to make quick changes to documents. It has improved over the time i've used it, as originally the font didn't always match and some sections couldn't be moved or deleted, but it now seems to have these features. On a couple of occasions I've needed to raise a support ticket, and the team are very responsive, helpful and provide a resolution quickly. The reason i've not given it 5 stars is because last year i had to edit a 60+ page instruction manual, and spent many hours over a couple of weeks trying to get it to work, but it kept crashing and not loading all the pages, which was frustrating and wasted a lot of time. In the end i gave up and redesigned the manual using another platform. Overall, great for simple editing and the basic package is good value for a small business.
