EPS Viewer

EPS (Encapsulated PostScript) is a great vector image file format and you can scale them up without loss of sharpness.  But PowerPoint doesn't allow them any more (a security bug, imagine that), so they need to be converted to a bitmap image first.  EPSViewer will do just that and can scale up in resolutions higher than one of those new-fangled 4K UltraHD TVs.  The fish below was scaled (pun intended) up to 10,000-by-4812, but higher is possible, and unlikely ever necessary.
