pdfFiller scores top ratings on review platforms
I thought the software was excellent. Did not like the "gimmick" of paying an annual fee in advance, then offering the same service at a huge discount. That makes potential customers feel like smucks.
I am retired and use it mostly for medical forms. A little difficult to learn how to begin but once I figured it out everything worked just the way I wanted and I learned more as I went along.
Enjoyable and functional.
Ease of use, functionality, and security features. I like the automatic lock out for the encryption and I enjoy the accuracy in identifying areas that need to be filled out.
That I cannot move folders within folders under the encrypted area. I would like to be able to drag folders into other folders. I would also like to merge more than 5 documents at a time.
