I have an illustration in adobe illustrator. The .ai file is about 23 MB. When I export it to .wmf or emf file to be imported into the Word, it becomes about 124 MB that is a lot. Importing such a big file into Word, makes it hard to even scrill up and down inside the document.
1. is there any better way to import vector illustrations in the word? I tried .eps as well, but the Word just shows eps file as an empty placeholder, why?

2. is there any way to force the Word to just show a preview of a special picture in Word and make it to show the best quality when it is printed to pdf? I do not want to use that option that shows all photos as placeholder.

BTW, the png and tiff produce raster and not vector pdfs and basically they are raster themselves.

thanks
