title_body: Kindle Paperwhite Custom Fonts
upvoted_answer: I understand it is possible to add new fonts without jailbreaking as follows:
  
  
  Remove DRM from Kindle files and make them convertible  
  Convert Kindle eBooks to AZW3 file with Calibre and embed the font in the Kindle file  
  Transfer the converted files to Kindle
  
  
  There's additional details at this article.  The article states that the method works with the current Kindle eReaders and the older ones that support KF8 format eBooks.  I believe this includes your 6th generation Kindle (aka Paperwhite 2)
  
  I have not tried this method myself, so "your mileage may vary."
