So far PDFfiller has been extremely easy to use and very useful! I previously used another program to convert and to edit PDF documents. Although it was also easy to use, this one is much easier and has way more options.

Fill it out!
Overall, I love when this is available to use for forms I need to fax or email.
I love the feature of being able to fill the form out online. Very easy to use and beats having to fill in by hand, scan and send.
I am not quite sure how to do this myself and have to ask IT to assist in making the form fillable for me.
