Kindle Previewer 3 — Beta
Amazon has released a new version of Kindle Previewer, the tool many developers use to convert EPUBs to MOBIs. It’s available for Windows and Mac OS.
Since it’s still in Beta, I won’t replace my existing Kindle Previewer version (2.941).
Here’s the link (note: I had quite a bit of trouble downloading with Chrome on my Mac, but Firefox downloaded without a hitch):
It’s worth reading all the FAQs, so scroll through the download page.
One highlight is the list of devices supporting Bookerly and Enhanced Typesetting. In fact, it mentions that you should keep version 2.941 on hand to compare Enhanced Typesetting results with non-Enhanced when viewing in Kindle Previewer.
Of course, Enhanced Typesetting seems to be applied within the Amazon ecosystem; we can’t add it (or Bookerly) as developers. So we can’t preview these features as we work.
Kindle Publishing Guidelines Also Updated
You can download them here:
The Guidelines address Enhanced Typesetting, but without saying ‘how’ to do apply it.
New Fixed-Format Wrinkle
The new Publishing Guidelines also describe (in a new Chapter 12) a version of the KF8 Fixed-layout format without popups. Amazon states this can be used when text is large enough so it doesn’t need magnification. This is all fine, but designers should keep in mind what devices and apps their books will be read on; small smartphone screens might mean that what seems big on iPad or Fire will still seem small on iPhone.
