On Calibre (which is my main converting station) when choosing mobi, there is not a KF8 option actually! so any help?
KF8 is the internal name of the new format. Select AZW3 as the output format in Calibre when converting files.
(You can also install KindlePreviewer and convert .txt and. .html files to KF8/AZW3 by opening them with it.)
Note that .txt and .pdf files usually don't convert well and converting .prc to .azw3 will not improve the quality.
