When I write out my own proofs by hand on paper, I use my own personal variant of Q.E.D. / square to finish out the proofs (its a cursive version of my initials).

I've doodled up this icon on paint and want to insert it into my proof environments in the end as its Q.E.D. symbol.

I know how to change the symbol to whatever using

\renewcommand{\qedsymbol}{text here}

But I don't know how to extend this to use an image file rather than text. Any advice appreciated!


This should be as simple as


where you can specify the options to suit your needs.

Here's a minimal example:

enter image description here





  This is a theorem proof.

  • Worked like a charm, thank you so much! If you don't mind, do you have any idea of how to make the \qedsymbol create a new line for the symbol and place it on that as to avoid extending the line height too much? – wjmccann Feb 19 at 1:04
  • @wjmccann: You could consider \smashing a too-large symbol. Something like \renewcommand{\qedsymbol}{\smash{\includegraphics[<opts>]{<img>}}}. – Werner Feb 19 at 1:22
