It's not already a picture (a raster image), so whether it compresses again (lossy compression, like a JPG has) or not (lossless compression, like TIF or PNG) doesn't matter.
I think this will work in Word, but I'm not sure. Choose File | Save As and select Webpage (HTML) from the "save as type" dropdown. You should get the File.HTML and a folder of supporting files. The image file would be in there.
Ah, nevermind. Just tested. Save as HTML does work. You have a PNG and JPG there. But it doesn't matter all that much because in Word 2010 (which is what I'm using here), I do have "save as picture" as an option on right-click, so I just saved it as a TIF from there. It's attached.
Too bad you can't get at the original drawings. Those are vector-based, and that would actually be best for print.
