It's excellent! Saw Vadim talk when @ TS Boston and switched over from docusign. Personally think that everything about pdffiller is better and would never go back. Highly recommend pdffiller to all of my friends.

Easy to use. Haven't found a form it couldn't handle. I had an issue recently where it would not allow me to save a copy of the completed form as a PDF on my computer. Weird. Otherwise 5 stars

It's a good program, convenient, relatively easy UI. Needing to subscribe to a function that was free for a time on the Adobe software, is an irritating feature of life in the 21st century.

This is an amazing service. Makes it easier when you cannot find the forms you need, otherwise.
My parents were unable to purchase mail forwarding services through Canada Post website. A Google search brought me to pdfFiller website and I was able to fill out the form easily. Canada Post really pushes to do these things online & we were unable because their website would not load.

I teach 3rd grade and most of the resources and district resources are in PDF or Doc Hub format. This does not allow my students to fill these kinds of worksheets out online. That was a problem until now. PdfFiller is saving me time and effort in preparing lessons for my students.
