    Yes but it involves a few steps. I do this for my Kobo Aura H20 for Kindle books. First, install Calibre ( Second, install the DeDRM plugin ( Third, install the Kindle for PC app and use it to download your Kindle books. Then use the Add Books function in Calibre to add them to your Calibre library. The DRM will be removed during import. The Kindle books are in your Kindle Content directory. Plug the Kobo into your computer and use Calibre to add the books to your Kobo; they'll be automatically converted to ePub before they're transferred.

    I found this out last week when I bought a Kobo Forma and started converting all of my favourite Markdown documents to epub to stick on there. Calibre even lets you create a TOC by specifying the header regex (#, ##, etc for Markdown), it's great! had to edit a few manually to tweak layout and Calibre ( has a nice editor for epubs built in.
