Plugin for post signature that offers changes in font size, links

Isn’t there a plugin out there that allows you to change your signature at the bottom of a post, specifically the text, font size, add links, etc, just like the post editor? Without having to edit html or edit custom files? Surely something like this exists, I just can’t find it. Just a simple plugin that I can insert a picture, my name, and some text with a few links. Anyone know of anything? Thanks
