pdfFiller scores top ratings on review platforms
This cost too much when you are on a fixed income! Your product is set up so we have to pay for each individual service that is offered. Pay to print, pay to download, pay to save, pay to highlight and the list goes on and on........
Still trying to navigate system. Like concept. Would like template in which I could answer set of questions and answers automatically are filled in in right spot on forms.
Over all really helpful, especially with me filling out awards and scholarships for grade 12. Only issue I had was when typing the text box wouldn't fit as nicely as I would have liked it to, so lines ran through the text and made it a bit harder to read.
PDFfiller is very easy to use
No instructions needed, so very easy to use.
The software is very easy to use, so other than a lower price, it is great.

I like that I can bring in any fillable document, it makes everything to do with a business much easier. It's just not very easy to do. I have to remember how to do it every time. Not sure if that is my fualt or if this is just not that user friendly.

What I like most with the PDF filler is the ability to secure and password protect a very important document. I like sending documents or exchange with staff for faster and easier collaboration and this software helps us do that while making sure the personal information are protected.
Nothing much as it serves the purpose that I am really looking for. I cannot think of anything that I don't like. I am satisfied.
Good Software - I would recommend to others
Good software. Did what I needed it to do. The layout could be a little less cumbersome, kind of busy when you look at the screen, a lot of icons/pics and made a simpler to navigate.
