What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
The learning curve is fairly easy and short. Still learning features as I go. I use the program every two weeks and generate four documents each time. I've been able to look up every document that I have needed and able to open and edit and print. There are occasions that he document will cut off part of the header or will not allign the text correctly. However, that's about 3% (or less) of the time.

PDFfiller is great if you need to edit/change PDFs This software allows us to fill out and share PDFs, vastly cutting down on our printing/scanning song and dance. No real negatives other than I wish it were free.

Don't quite understand how it works as I am not a computer person except to do genealogy, and write. One cannot operate a computer without it. At least this is what I'm finding out. It all seems automatic, I would like to know more about it's function, Why's and what-fores, instead of just logging on and it appears. All I know is that it is a major function for downloading photographs and some documents. There should be a tutorial offered to those who are senior citizens and so many things are automatic. It takes understanding its function to a non-software-computer person. Guess more instruction would help.

PDF Filler is a great website for me to… PDF Filler is a great website for me to use. It's simple and convenient since I don't need to fill everything by hand. The only issues I have are filling in the date because I'm required to manually select the day, month, and year. Another issue is the website automatically switching to the next page which is annoying because I want to check all the fill ins are correct. Lastly, the layout of the website is rather confusing because I had to spent a couple of minutes figuring out how to import documents and other stuff. That's why PDF Filler gets a 4 star rating because of these mild inconvenience.
