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):

The previews and thumbnail images appear in the web view and for customers using Files On-Demand in Windows 10. Here’s the full list of file types supported. 3-D Modeling/Printing: 3MF, COOL, GLB, GLTF, OBJ, STL.

In Windows 10, when you hover over a taskbar button of a running app or group of apps, a thumbnail preview appears on the screen. For a single window it shows a single thumbnail, and for multiple windows it shows a number of thumbnail previews in a row. Windows will show them if someone implements a Thumbnail Provider for the 'epub' file type, see Thumbnail Handlers (Windows). If anyone's minded to do so, then they might want to consider doing an 'epub' Preview Provider and an IFilter for 'epub'.

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.

I’ll look into this more as time goes on, and update as needed. I’d love to hear from anyone who has used the new Previewer. What are your experiences? Crash much, or not at all? Javascript errors? Enhanced typesetting present? Comments on the interface itself?

Kindle Publishing Guidelines Also Updated

The Guidelines address Enhanced Typesetting, but without saying ‘how’ to do apply it.

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.
