I worked fine for my needs of filling in a PDF file and saving it with data. I would like to see the ability to CREATE a fillable PDF file that I could distribute to others to fill out, save, and return to me.

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

Great for PDFs! PDF filler is a great way for me to edit PDFs that clients send me. It is also very handy for finding my own PDFs that I need for a variety of reasons. I love how useful this product is. It is also really easy to use once you get the hang of it. The database of forms they have to search and use is also incredibly helpful! It can be a bit hard to use at first, especially if you aren't familiar with PDFs. I typically have to train an employee for about 30 minutes before they can really understand and use all of the features that PDFfiller provides.
