Simplified accuracy ! pdfFiller simplified and shortened the length of time; when I needed to complete filling out pertinent documents. My first experience with pdfFiller was when I had to do taxes. All the technical difficulties with filling out tax documents no longer existed. There are no Cons to specify, except my fears that this app is a "too good to be true" app. If you knew that before this app came along, PDFs were untouchable and un-editable.

What do you like best? I like that I can pretty quickly add fillable fields and combine documents. I create printable packs for travel and RV life and this program has been so great for finishing touches on products. What do you dislike? When I add other documents to an existing one (combining) it renames the document and also makes a new version. This means I sometimes have to search through all the "documents" and even open them up to find what I am looking for. It can be pretty annoying when working on a large document with 20+ pages. What problems are you solving with the product? What benefits have you realized? I am solving the problem of needing a PDF editor. I initially needed it for signatures and filling out PDF forms for work. Then I started to use it for personal use in adding fillable fields to products I create, and bundling multiple pages together into PDF format.
