My experience on line with anything new is always a bit frustrating because of my inexperience. That said I was able to complete my form and print it out in one sitting

easy, well organized, love the signature options especially. Ability to share and distribute is a fine function. I live in Germany and did my girlfriends USA taxes all electronically and send to her to sign and submit.

Great Value for the features included PDFfiller has all of the features I need. The ability to combine documents, fill forms and add signatures. Navigation is not intuitive and the user interface is cluttered.

Searching for specific wording in a .PDF file My request for assistance with an issue I didn't know how to fix was answered very quickly and I was back to work. Unlike most support with other software companies where you wait 3 days for a response requesting additional information then another 3 days for a response and usually goes on and on. pdfFiller was right there and stayed with me until the problem was solved. Anyone dealing with .PDF files and not using pdfFiller is losing out.
