eBook formatting guidelines for  Smashwords’ file processor are  specific and must be strictly obeyed  to get your eBook into their premium  catalog. The eBook conversion we  do for you will meet all of these  guidelines while keeping your eBook  looking just like you designed it.  When you send your eBook to  Smashwords, their file processor  won't give you any errors and we've  never received a rejection from the  manual reviewers so you can have  the confidence that once your eBook  is reviewed, it'll be approved. 

Though ePUB is the format of choice  for most ereaders on the market,  eBook conversions to the ePUB  format are typically requested for use  with Barnes & Noble's Nook Press  system. Publishing through Barnes &  Noble’s Nook Press system has only  one real guideline: Look good. It  makes sense that if your eBook  formatting doesn't look good, the  content is irrelevant and if you don’t  send up an ePUB file there is no  guarantee what your eBook will look  like after their system processes it.  We’ll send you back an ePUB file so  that when your eBook goes live  you’ll already know it looks good. 

eBook conversions for publishing  through Amazon’s KDP system for  the Kindle are the most popular  request we get and this is where  you will usually make the most  sales. Publishing for the Kindle is  similar to what you go through at  Barnes & Noble, though instead of  ePUB files they use the MOBI KF8  format. Also, like Barnes & Noble, if  you don’t send your eBook in the  final format (MOBI) there is no  guarantee on its final look. We’ll  send you back a MOBI file that  meets KF8 specifications so that  when your eBook goes live you’ll  already know it looks good.
