In iTunes after connecting your iPad select the Kindle app within File Sharing. Drag and drop the KFX file there. The book will then show up in the Library view of the Kindle app. (See attached images.)

Amazon has released Kindle Previewer version 3.68.0. It is compatible with the current release of this plugin.

Is there any way to allow converted ePub to KFX to have manga mode?

I know I can use Kindle Create to do it, but this method isn't good for converting multiple chapters/files. (Either one by one manually or merging them in one file)

Is there any metadata, like fixed-layout metadata, that can trigger manga mode? (before converting to KFX)

Amazon has (poor quality) documentation on the EPUB requirements for creating comics and manga here: Creating Fixed-Layout Books with Image Pop-Ups or Virtual Panels

I don't know of any way to do that. This plugin uses Amazon's Kindle Previewer for conversion of EPUBs and that software does not support fixed-layout books.

I allowed Kindle Previewer to update to 3.69.0 today, but didn't think to check here first to see if it was compatible with the plugin. Do you know if it is?

I will be buying a device for reading books , especially .KFX files for it's enhanced typesetting feature on kindle. answering these questions will be much appreciated.

1. What is the best device to read kfx files? i have kindle fire hd 10, realme pad and kindle paperwhite in mind
2. Does Goodreads integrations work well in kfx file in kindle fire devices? Does it automatically update the status on goodreads to 'Reading' as soon as I start reading it? Or do i have to manually do it?
3. How is the GR integrations in kindle paperwhite for sideloaded kfx files? Does it automatically update the status on goodreads to 'Reading' as soon as I start reading it? Or do i have to manually do it?
4. Is there any way to get the Goodreads integration working for sideloaded kfx files on Kindle Android App? GR integrations for sideloaded .kfx files don't work on kindle android app as far as i know. By goodreads integration on kindle android i mean the "About this book" from the 3 dot menu while on a Amazon-bought book. I'm hoping it's the same in Kindle Fire devices as the kindle android app.

Yes it is. (Sorry, I forgot to make a note of it in this thread when that version was released.)

There is no single best device. Which is best for you will depend on your needs. The Paperwhite will be easier on the eyes for long reading sessions or outdoor reading. A Fire tablet will show color and has the ability to page though books quickly. The user interfaces are different, but in terms of KFX rendering they are about the same. (I am unfamiliar with the realme Pad.)

I don't know. I do not have a working Fire tablet at the moment.

When you first open a book there is an "About this Book" popup dialog where you have the option to "Mark as Currently Reading" in Goodreads. You can also do it manually by long pressing the book in the library and selecting "Add to Goodread Shelf".

For this to work the KFX file must be linked to the equivalent book for sale by Amazon by setting the ten character ASIN.

I do not know. I have not been able to get Goodreads integration to work in Kindle for Android, even for purchased books

Version 1.65.0 - 16 Nov 2022

Update the conversion option documentation to reflect that Kindle firmware 5.15.1 will display cover thumbnail images for personal documents in KFX format.

Detect Kindle Previewer versions up to 3.69.0.

There is no good device to read XFX. XFX is an awful format designed so Amazon can keep you in it's walled garden. They designed KFX so the DRM cannot be broken.

IMHO, you are best with a device where you get enhanced typesetting and the ability to remove the DRM.

Got some weird problem here.

Got a (copyrighted) EPUB. Opening that file in Kindle Previewer 3 directly cause no problem, but conversion in calibre failed with this weird error:

E21018: Enhanced Mobi building failure, while parsing content in the file. Content: <data-AmznRemoved> in file: OEBPS\text\cover.xhtml line: 4294967295

Which honestly make no sense to me. I tried to pick up immediate EPUB created during conversion and, sure enough, also cause the same problem when I opened that immediate file in the previewer. But there are no <data-AmznRemoved> anywhere in the file (and the line number is just 2^32-1) And since the original file and the file exported from calibre opened fine in Kindle Previewer, I think something calibre did is causing problem...

Do you have any idea? I can send you both file via email if you wanted (I still have your email if you haven't change them, but I don't want to send it without prior notice)

I don’t know what could be causing that error. Go ahead and send the files and I will look into it. My email is unchanged.

Thanks for providing the file that demonstrates the problem. I was able to determine that the error is triggered by a <title> element inside of an <svg> image being given a style with display:none. For some unknown reason calibre is adding that unnecessary styling during the first step of conversion for this EPUB.

The next release of this plugin will remove that style before passing the EPUB to the Kindle Previewer so that conversion can complete successfully.

Thank you very much for investigating and fixing.

I can also confirm that if I removed the <title> tag from the <svg> in question (it's not like the tag is serving any purpose), then it converted beautifully.

I'm not able to convert from EPUB to KFX. Conversion Failure Reason says Log File is missing. The annoying part is that the logs show the message "Book converted successfully!" right before failing. Had a look at the code on github but wasn't able to figure out whats going on. It seems like some of the output from the conversion ends up in a different folder in \Temp from the one that contains the following log, but that might be intended behavior.

Here is a pastebin with the output
