Loving it so far. Wish the search for documents in their library was easier to find, but other than that, I've been very happy with ease and quality.

This program is the best PDF editor/publisher , I have ever used. I especially like the ease of uploading images and placing them onto page. You are able to make adjustments, easily and can print specific pages and email, fax and or save complete documents or just a certain page, if you wish. Great program.

I think this is the most user friendly app and the customer service experience has been outstanding. I have MS and am computer challenged. Thank you for making my life a little easier.

What do you like best?
The program is easy to use and super convenient. Your documents are always with you on the server PDFIller provides.
What do you dislike?
Getting in touch with a person in customer service is impossible and emails to cust. serv. have not been answered. I originally signed up as a single user; but then as my needs expanded at my office, I added and paid for three more users. For a while everything worked without issue, but then the other three users could not log-in and the different prompts in my dashboard were saying the subscriptions were active and to this day my office staff works through my sole account which can knock someone off in the middle of something.
What problems are you solving with the product? What benefits have you realized?
The fax benefit is awesome. I use the program with my insurance agency. It is way more user friendly than Adobe and you don't need a separate service to send a client a form to sign.

Great for making a pdf fillable planner I've tried Adobe & SODA pdf & both were a nightmare:/ From ctrl not being able to multi-selesct, text boxes not duplicating with a new names (meaning I would have to re-name or re-make 10000 boxes manually...) I've had a really good experience with pdf filler! It has everything I need to easily add fillable fields & make my planner useable. Thank you finally a product that matches my requirements.

It took a like while for me to figure out how to do... It took a like while for me to figure out how to do what I wanted to do. But once I did, I was able to create the doc I needed. The part I liked best was the guidelines to put the fillable boxes in line with the other boxes in the document.
