First, a note to people still downloading the previous version: STOP IT. That is what happens when you link directly to a file instead of the download page.

Things I forgot to mention:

• The save as 8-bit colour output is currently using the inbuilt gif compression to reduce it down to <256 colours. It isn’t very good at it, so the output will be much better if I ever get around to writing my own octree quantization code (or find some gpl code to do it).
• To get the best results, check the invert output button so it has white text on black, then “save as colour text”, and save as 8-bit XHTML. I’ve been meaning to write some tutorials for a long time.
• If you want to save it as an image, to print or whatever, I would suggest the Save As Image plugin for firefox. Then just load the html into firefox and you rightclick to save the page as a png.
