If you have been using desktop based app, you might know how easy it is to add files to your notes, however, don’t fret if you are a Evernote web user, since starting today, Evernote web allows users to drag and drop files to their web interface. Free users will be able to attach images, audio and PDF files to their notes using drag and drop.
However, the new feature is only available in Google Chrome and Safari right now. Users can drag and drop the files on the notebook in the left-hand panel to create a new note, or drag and drop the file into any note too.
More info on this at the official Evernote blog.
