Hi. Evernote now saves web pages inside HTML (more or less) 'frames', but I don't know what would happen to a text document that was part of that page - as far as I remember there was never any automatic reformatting to PDF or annotating of content; trying to edit a note containing a web page got you "unusual" results because new entries would alter the hidden HTML content of the page. If you clip as an image, it's possible to annotate the image, but editing web pages or their content has never been possible.
