I have tried various services that allows bulk conversion of html-files to pdf, for example Wondershare PDFelement. The conversion of for example an Evernote note created as an email with an attached pdf, first exported as html from Evernote, and then converted into pdf, is made as a pdf where you can see the email and the pdf as an icon. If you then presses the icon for the attached pdf, it opens as a pdf in a separate window. I need the two files to be within the same pdf. I can see that it is probably problematic from a programming view to make what I am after, but hope that someone should know a solution 🙂
