In Visio 2013, I have a diagram with pictures that I need uploaded onto a website. Once I save it as a web page, the pictures look blurry compared to how crisp & clear they look in the Visio 2013 drawing file. I've tried saving the web page as all different kinds of files (VML, SVG, XAML, PNG, JPG...) and nothing seems to make a difference. Any suggestions on what I can do?
