Here’s a website where you can type in some TeX code, click a button, and get back a GIF with a transparent background. Handy for pasting equations into HTML.

For example:
Update (December 2014): The site mentioned in this post doesn’t seem to exist any more. Some alternatives:
- Roger’s Online Equation Editor
- Mathb.in
- Mathurl.com
That’s pretty cool. I also happen to like jsMath just because I think its a very elegent approach of embedding TeX into a simple javascript processor in a portable way. It also makes the resulting HTML code very readable which I like instead of embedded graphics.

Thank you! I was looking for a tool like this to share problems with my students. An online tool that live displays Latex output reduces the friction of learning a full latex package for my students.
