What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
The forms are good but they would be much better if the user could "snap to" the proper location when typing into a box. Without a "snap to" type guide it is difficult to place the cursor in the correct location within a box and especially difficult to get columns to line up.

There are things I still can't figure but overall, I am getting the hang of it and it seems fine. It takes a while to go between pages but that could be on my end.

Our previous subscription was deactivated because no one seem to know the login or password for the account. It was assumed a temp employee had subscribed who is no longer employed. Difficulty accessing and filling online forms prompted us to re-subscribe. This morning's experience has been great and we plan to continue using this application.
