Maybe https://github.com/niklasvh/html2canvas can help for this

For the svg, there really isn't much to do except ensure there's no translated stuff or such that wouldn't work outside the context For the png, why not, if we have good tools as well to make downloadable the base64 version of the canvas maybe or such?

just a simple question : why do we need this export ? is it for easily taking a screenshot and share it on social network ?

I'm afraid that "printing" an html document is quite hard and unstable according to the browser. I will wait a bit before doing such a thing.

Actually the objective envisionned was to easily build collection of views on multiple texts to do some visual comparative analysis. I guess this could be handled through some kind of PhantomJS scraper. No priority on this in any case
