I love it
I love it! I am a teacher and due to COVID-19, I have had to learn how to teach online. This program allows me to give feedback directly on the page for each student, as well as create and personalize assignments. It's been a lifesaver!

The overall experience was good, the only thing I would say is to increase the number of signatures from 10 to 100 in the case of signatures for the same document.

Took a bit to find the "how to use Zapier" tricks (Zapier had a link), and to learn how to use Fillable Fields properly. However, once over that hump, this service is fantastic. My workflows will be faster and cleaner from this point forward!!!

A perfect user-friendly PDF Editor
`*I usually don't look forward to doing PDF editing as it is usually a nightmare. Nothing lines up, missing a feature you need, doesn't save correctly, or you can't send it, etc.
This is the first PDF editor that I actually have fun with, super user-friendly, fast learning curve, yet looks professional, is feature rich [in fact it has features the others don't have], and no problems saving and sending or later editing it again down the road. I am just ending a one month free trial offer and will gladly renew it as my permanent PDF editor.

When I first started using PDFfiller (couple of years ago) I wasn't impressed with it - it could have been because of a lack of experience. I had problems with lining up numbers or letters within the document. However, now it is a breeze and this program is great. I am beginning to depend on it a lot. Bottom line - it is a great product.
2021-03-16
What do you like best?
Ability to edit pdf files and general ease of use
What do you dislike?
Limitations on how many files I can upload and the fact that it opens the files immediately, If I want to merge a newly uploaded files with previously saved files on my dashboard, it creates some unnecessary steps.
What problems are you solving with the product? What benefits have you realized?
Not really any problems - just a few areas the program feels clunky.
