I'm trying to use the "sign" feature in Acrobat Reader DC.
The online instructions say it should let me choose a .jpg, .tif or a bunch of other formats.
However, when I try to select one, Acrobat won't even let those show up as options. It will only consider .pdf files. And if I make the signature into a .pdf, it has "unknown error" trying to use that as an image.
So how do I make this work?
1. Please post a link to the instructions you are trying to follow. Very often we find that the problem is that the instructions are for a different product.
2. Please give the version of Reader you are using (from Help > About, a long string of numbers and dots like 2017.1244.23234 or 11.2.34).
