> Isn't Google's viewer really the default PDF viewer in Chrome? The one which doesn't add a toolbar or any tooltips that are popping up despite my mouse not hovering over them. No, it's not, unless, Google figured out a way to install their PDF viewer plugin in my Firefox without me noticing. ;) The link 6ren posted is to Google Docs's file viewing component, now sold separately: https://docs.google.com/viewer https://docs.google.com/viewer I'm not completely sure, but I think that for PDFs what the Google Docs viewer does is (1) generate a PNG image of each page, (2) extract the text and put in on the page as invisible HTML, positioned carefully to correspond to the PNG. The point of (2) is that it makes text selectable.
