So far printing doesn't work when printing directly from filled in form. I need to save it to my desktop and open in my pdf application and print from there.

I preveiously gave the program a low rating before technicians showed me that my problem was user error. I find PDFfiller a great addition to my daily work. I can fill the forms in and also go back and edit. Love it!

Needed an online PDF editor for contracts, works better than expected! I can sign and edit PDF files anytime, anywhere. The availability of it from any device, anywhere. All the platforms are great both the web and local apps. Sometimes it's laggy because it runs online but I suppose that's the tradeoff of having it available everywhere.

It was easy to use and did want i… It was easy to use and did want i needed to do. However, we starting I selected monthly only to discover it is charging me annually after registering. I didn't like that. Kind of expensive at that rate.

What do you like best? I subscribed to pdfFiller because a vendor sent me a pdfFiller form document that I needed to print. I canceled within the 30 day free trial period before my company card was charged. The cancelation was easy and the PDFfiller customer support desk was very responsive and professional in explaining a small temporary charge to my card. I likely will end up a customer. What do you dislike? There was nothing to dislike in my experience with pdfFiller. What problems is the product solving and how is that benefiting you? You are making this review process too tedious. I cannot type a novel. It seems like a very professional, well-run company and good product.
