Kindle Previewer version 3.32 and KPF

jhowell · 08-14-2019, 09:11 AM

Amazon has released version 3.32 of the Kindle Previewer. The major change is the introduction of a command line interface that can convert source files into KPF format. It also supports batch conversion of multiple files at once. Once a book is in KPF format it can be viewed with the Previewer GUI or uploaded to Amazon for publishing.

This provides a new possible workflow for publishers. It will be interesting to see if there are any differences in the resulting Kindle book if it is published using a Previewer generated KPF instead of a Master MOBI from kindlegen or a source format such as EPUB or MS Word.

KPF (Kindle Package Format) is a variant of KFX, the format that enables Enhanced Typesetting. Amazon's Kindle Create and Kindle Textbook Creator software have produced this format for some time. The KFX Output plugin for calibre is capable of converting KPF format into KFX that can be sideloaded to kindle apps and devices, a feature that Amazon does not currently provide.

Quote:

Usage instructions: kindlepreviewer <input> <-command(s)> [-option(s)]

Input: Specify the input file name here when processing a single file, or the input folder when processing multiple files.
Command(s): Include at least one of the commands specified in this table:
- -convert
  Create a KPF file in the specified output path or a Mobi file if the book doesn’t support Enhanced Typesetting. Use the Enhanced Typesetting-compatible KPF file to open the book in Kindle Previewer's graphical user interface.
- -showpreview
  Open the converted book in Kindle Previewer's graphical user interface. This will first convert the book, and then open it for preview.
- -log
  Use this option to generate only the log files for validation without generating a KPF or a Mobi file.
Option(s): Choose any of options specified in this table (optional):
- -output <output path>
  Path to the output folder. Use this option to specify a preferred path to store output file(s) instead of the default path (input folder).
- -locale <locale-option>
  Specify your preferred locale. Use this option to set the language for conversion log messages and the Kindle Previewer user interface. Supported locales:
  - en (English)
  - de (German)
  - fr (French)
  - it (Italian)
  - es (Spanish)
  - zh (Chinese)
  - ja (Japanese)
  - pt (Portuguese)
  - nl (Dutch)

Doing command line stuff on Windows is so ugly and unpleasant. Why couldn't they implement it with the UI?

Converting in Calibre from KPF to KFX blew up with this error:

Spoiler:

I do get errors when I convert it with kindlegen, which I've been blithely ignoring:

I suspect that this new CLI is intended as a replacement for kindlegen.

I agree that it would be nice if the export function of the Previewer GUI would allow KPF as an option. Perhaps in a future release.

The problem does not appear to have anything to do with the kindlegen warnings. By using calibre's GUI to convert from KPF to KFX you are actually converting from KPF to EPUB and then from EPUB to KFX. In this case the conversion to EPUB is failing due to unexpected content in the KPF file that the KFX Input plugin cannot handle.

I would like to fix this. It would be helpful if you could post the source file you used, as long as the book is not under copyright. (If it is still under copyright you could feed it through the ScrambleEbook calibre plugin to remove the text while retaining the formatting.)

If you use the command line interface of the KFX Output plugin it will avoid the step of converting to and from EPUB, which is part of calibre's GUI conversion process. That will repackage the content from the KPF file into a KFX container.

Thanks for that!

I was able to duplicate the problem and will be able to fix it in the next release of the KFX Input plugin.

If all I want to do is convert an epub file to kfx I'm guessing that I don't need to use the command line interface to kindle previewer 3 to make the kpf and can follow your instructions for generating the kfx using your kfx output plugin?

That is correct.

Hello jhowell! What does this mean, CLI is intended as a replacement for kindlegen?

Does this new KindlePreviewer not have kindlegen inside? Can one still export a mobi containing KF8 using this new KindlePreviewer?

Thank you

Yes it has kindlegen and can export MOBI. The new CLI will even produce MOBI if the conversion to KPF fails.

It is just my supposition that in the long run Amazon will want publishers to run their books through the Previewer and publish using KPF instead of using kindlegen and MOBI.

It is just a guess at where they are headed and may never happen.

Thanks jhowell!!

Trying to wrap my brain around this ... what is the point of KPF? What advantage or purpose does KPF have over a KFX bundle of files or a single monolithic KFX? I.e., why wouldn't Amazon simply have KindlePreviewer convert to KFX? Is it the encryption thing? Does KPF have no encryption? Is the idea that publishers convert to KPF then upload KPF to Amazon, where encryption is added as it gets converted to KFX?

Thank you!

At the lowest level both KPF and KFX formats use the same underlying data representation (Amazon Ion) to convey book content. The difference between these formats is analogous to the difference between a Master MOBI produced by kindlegen and a .azw3 file delivered to a Kindle.

KPF is designed to meet the needs of the publishing process. It is a single, usually large file. While it is zipped for transport, whe main internal file is an SQLite database designed for fast access, rather than compactness. Images are full resolution. And the original source files are included in case Amazon needs to re-convert the book at a later time. There is no provision for DRM, but there is a fingerprinting mechanism used to make sure that the content produced by Amazon's tools is not altered afterwards.

In contrast KFX is designed for delivery and reading. It is tailored to each device type. Images may be downsized and converted to black and white. Content is compressed and split into multiple files, allowing the customer to begin reading while the download to the device is still in progress. And there is DRM.

Thank you jhowell! As always, you are a wonderful source of enlightenment

Since one cannot upload a kpf file to Kobo, Apple, B&N, etc, it has the great advantage from Amazon's point of view of discouraging self-pubbers from selling their books elsewhere.

odamizu just an egg Posts: 1,587 Karma: 4300000 Join Date: Mar 2015 Device: Kindle, iOS	Trying to wrap my brain around this ... what is the point of KPF? What advantage or purpose does KPF have over a KFX bundle of files or a single monolithic KFX? I.e., why wouldn't Amazon simply have KindlePreviewer convert to KFX? Is it the encryption thing? Does KPF have no encryption? Is the idea that publishers convert to KPF then upload KPF to Amazon, where encryption is added as it gets converted to KFX? Thank you!
