Sometimes it is hard to figure out the forms. I thought once I type in one form, that the information would replicate into the forms below, but that didn't happen.

It think it can be very useful once I get the hang of it. Disappointed that for a yearly subscription of $72.00 you don't get access to the erase feature. This feature is even free online. Do consider and include it.

On first blush,this is a fine tool. I have a limited number of documents. So this works great. Simple. Easy to follow. Support answered some not so obvious questions quickly and easily. Well done. I have one question or suggestion..I would like to merge a couple of my documents...but don't want to pay for a full upgrade for just two or three uses. Can you offer a "yeah we'll let you do this" one off pricing for someone like me? Would be very helpful. (I will also say I tried several of the competing products...and this was far easier to use)

Pdffiller suits almost all my needs… Pdffiller suits almost all my needs once I get my files there. If I could have a way of "breaking" my files heavier than 25MB to get there OR if it accepted larger files... it would be perfect!
