What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
I like the program a lot. You recently changed the format a little. When I want to save a document to my computer, I can't tell it where to save it; it automatically saves it to my downloads, which I do not like. Before you changed the format, I was able to save a PDF completed document to whatever file I needed to on my computer. I would like to be able to do that again.

I like the ease of use. I do think the help system needs and upgrade. Should have a searchable index. It is hard to find topics. I am an experienced software guy and just want to find out how to do thinks.

It keeps mixing up my two accounts - - one subscription with an aol email address and one free account with my fire dept. address. I believe it's due to my MSOffice password settings.

PDFfiller Review Overall, the experience is very good. I plan on using it for a very long time. It's very easy to navigate. PDF Filler makes it easy for small business owners as myself to have the professional look when conducting business. It's a lot of features that I don't need. This sometimes causes confusion and extra time navigating around the site.

Easy to Use PDF Filler It's very easy to upload documents and complete the forms. We use it for all of our documents. I sometimes have trouble with my signature loading. My printed signature always loads but my written one does not always load. I'm not sure what causes the signature failure but it is sometimes a problem.
