I like it but felt that my "free trial" was a bit of a scam. I spent hours on a document, learning your program but was unable to print it. I don't like being "forced" into purchasing a product.

The Product concept is very nice the use of tools are simple. Things that I don't like are is that you are required to select Continue in Browser when click the Hyper Link, this for me is an unwanted and in needed step. The App I wish would allow you to search your fillable files, without the Link/Code or QR code you cannot use it. Would be more willing to use the App if this was a feature.

I have used PDF filler often to complete PDF forms. The program is very user friendly. I love it! I love the ease of use it creates when completing documents. It takes the hassle out of completing some of the complicated documents. I really don't have any negative feedback about the software. Sometimes the text of the document overlaps and I have not figured out how to avoid that from happening.

The fill in is with text boxes like in word. That works well. It worked well. Not as good as a PDF document that already has input fields but much better than printing the PDF document and filling it in by hand,

Great to use especially working from home I have been working from home and Sarah PDF has been trying amazing. It is very easy to use and the way I am able to merge my documents and download them is great.

Wish I Could Change Color of Signature I enjoyed this tool and site. However, I wish there was just some way that I could not only change the font for my signature but the color to blue as well.
