Save as Web Page saves the document as an .htm file, preserving all the
formatting of the Word document so that, if desired, it can be resaved as a
..doc file without losing formatting. "Web Page, Filtered" also saves as .htm
but removes some of the formatting data for a more efficient Web page. It is
still, I am reliably informed, extremely bloated and ugly HTML, however.
Both of those file types save illustrations as separate, linked files. This
can be extremely useful if you are trying to extract pasted graphics as
separate files in JPG or GIF format. "Single File Web Page" uses the .mht
format which, as I understand it, somehow embeds the graphics in the file
itself (just as the Word document does).
