I fill out a lot of forms from different organizations. Found PDF Filler after searching for a federal form. It was the top result and I started using it from there. Some organizations do not even realize how they have deployed PFD files. When you show up, or fax them their completed PDF file you get some odd reactions.

I really like this program. It accomplishes exactly what I need it to do and is very easy to use. Just upload any doc, input the data, and save/print it. That easy!

I enjoy the forms you can search and fill out and all of options you have to mail out the forms. The site just needs to be a little bit more easy and user friendly in regards to filling out forms and form searches

Works well but continues to have security issues in connecting with my Google Drive account. Each time I open a PDF in Drive using the PDFFiller App, I get an Unsafe warning. Please clear this problem up. I don't have the time or energy to do your survey right now, perhaps in the future.

Excellent support and customer service I registered for an annual membership, but I didn't pay attention that the membership fee is calculated in US dollars. I live in Canada and it was expensive for me. I emailed support department to cancel my membership and they responded in less than an hour and sent me a full refund. I appreciate the excellent customer service and proper support, polite and professional behavior of the staff.
