Am new to PDFfiller so here are some initial comments: 1. an "undo" button would be nice 2. when sharing a document and adding comments/instructions, it would be helpful to have the option to pull up the document to be shared for reference.

This is an awesome tool to have and it makes filling out documents way easier. I had to fill out a document in which everything has to be perfect and the PDFfiller helped tremendously.

PDFfiller has helped me take care of both business and personal matters while on the go. The program/service has kept me from having to find a printer and print, sign, etc. I can just pull up a file, electronically sign and send back. Thanks PDFfiller!!!

Site could be more mobile friendly. I'm still learning but so far it has done exactly what I needed and greatly improved my ability to get the docs back I send.

What do you like best?
As a Realtor, my whole business is based on electronic documentation. PDF filler is kind of named poorly, because it really is a PDF editor. It allows you to easily change almost anything on a pdf document...across both desktop and mobile platforms. It simply works as you'd expect it to...every time. I use it practically every day.
What do you dislike?
I wish there were better tools for generating lines (how about a toggle into and out of orthagonal for a line?) It should allow deeper zooming with a thumbnail view showing where you are in the overall document. I like my pdfs to look perfect and sometimes these limit me in that goal.
What problems are you solving with the product? What benefits have you realized?
A Realtor literally lives or dies on his/her electronic documentation. This tool lets me master the changes that inevitably occur with documents. I use it every day.

Easy to use with all the features we need for a pdf The way you allow to edit document is really great. Adding pages and adding images to pages works really well. Finally some application that has almost all the features we need to create or edit pdf.

It was actually nice, easy and convenient to use. It is just that I find it expensive so I revert back to my old ways means manually filing or writing in forms. :)
