What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
Great. However, I need to type vertical on the forms I am filling out and am not sure PDFfiller allows this process. There are two pages that I prefer to print on one page but I do not see this option when I am ready to print.

I like that my information is saved and I do not have to keep writing over my applications. I can get it quickly when I see a job I want to apply for.

Everything has worked great and while I honestly don't know what there are companies that still use Fax, they do exist and I need to work with them. Love PDFfiller and everything it provides.

The form 1096 is not current in the video shown - it shows 2012 and the number 7 is different for 2016, so would like an explanation of what NEC means. Thought I could use this for 1099 and also 1096 but still need to use IRs forms to send them, so dissapointing. Wondering what I will use this service for - does it allow ALL pdf files that I receive to be opened and edited? If so, then useful. Otherwise, probably short lived for me.Thx

There doesnt seem to be alot of "man in the street" logic to how you explain things. It seems to be written by Code cutters or IT people. Lots of simple things like , I look up how to save a document. You say : Save your document by clicking the 'Save as PDF' button in either the "MyForms" . There is NO such button only a "save as" button. Also Where is the "My Forms" page? is it named as such or .... ????Bascally though, its a great piece of software. You just have to get a REAL human being to rewrite instructions.
