				MOBI to EPUBv2 or EPUBv3?
			 
			
			
			I have an older MOBI file that is converting to EPUB with content out of order. 
		
	
		
		
		
		
		
		
		
		
		
		
	
	The MOBI file is readable and flows correctly in the Calibre viewer. I've converted several other MOBI files that originate from the same time period to EPUB with no problem. I figured out that converting using EPUB 3 worked. Is there a way to tell which format will work better beforehand, considering it's coming from a MOBI format? Thanks!  |

			unless you have a particular reason to prefer epub2 always use epub3. That said I cant think of a way in which epub2 vs epub3 would make a difference converting a MOBI file unless it was actually a KF8/azw3 file with EPUB 3 specific markup.

			I can't see how a Mobi to ePub 3 would be any better then an ePub 2. The Mobi has no ePub 3 code and nothing needing to be ePub 3.

		  Where would it get the info to UPSCALE?To me, this is like taking an old B+W film and expecting the conversion to not only colorize, but Upgrade to 4K and make it into true Surround sound ![]() OTOH If this is just the first step, of a editing process to recode, then go for it  |

 Mobi was nearly 7 years obsolete when Amazon bought Mobipocket in 2005. The first Kindle was 2007. A dreadful format, though for a plain novel a Mobi to epub2 mostly is fine unless they have indented with multiple blockquotes (replace with one <p class="big-indent") as that can result in an ureadible column of letters. Usually some edit is required.·  |
