Kindle to utilize epub format in late 2022

Or instead of removing all three, try them 1 at a time and check the output.

Or try Fonts -> Disable font size rescaling

I dunno... try various options 1 at a time until you land on one that makes a difference?

It's best to learn HTML/CSS and remove the code from the CSS as needed by hand using the Calibre editor.

From an initial look the new epub looks the same as the books purchased from Amazon and the Star Trek epub from above.

I’ll do some more experimentation later but the first signs are very promising.

Many thank. I’ll report back.

That's a bad idea. You don't know what will happen to the eBook when you do. You are best to edit the code to fix the problem.

Load the ePub into the Calibre editor, then under the Tools menu, select Remove unused CSS rules and then copy the CSS code and post it here (in a code block) so we can have a look at it. Thanks.

And skip Amazon. Use USB transfer.

Converting the epub to mobi and back again seems to work ok on my Kindle which is great.

However the same can't be said for the converted book in the Kindle IOS app.

See the two screenshots below - epub on the left and purchased from store book on the right. The formatting seems massively different.

If I go to Remove Unused CSS in Calibre it says "No used CSS style rules found, No unused CSS selectors found and No unused stylesheets found".

I will post the CSS outputs.

I've just checked the Star Trek epub on both my Kindle and the IOS app. As above, it looks fine on the Kindle but on IOS the formatting matches the screenshot on the left above, whereby the line spacing is much less.

It was definitely worth testing all this but it appears that if you want consistent formatting between devices you do have to get your books exclusively from the Amazon store and not from a third party store.

It is if you want to use Whispersync.

I gave up on whispersync the moment we can't have covers anymore on send to Kindle books (at least until August).

Why not just keep sending mobi files until august? Covers still work fine for those.

No custom fonts and no boldness adjustment.

Ah, ok. I've never had those in my Kindle docs before epub support, so I guess I'm not really missing them now. I'd rather have cover thumbnails and Whispersync. To each their own!

I may be misreading this but do you expect covers to work on send-to-kindle books after August?

As far as I know dropping MOBI from send-to-kindle will remove the possibility of having covers when using that feature.

A boy can dream. But no, I'm not expecting it, per se... but it'd be nice. What I *am* saying is that I intend to keep using MOBI format with "Send to Kindle" until they stop accepting that format in August. Thus, I continue to get proper formatting and cover thumbnails in the meantime.

Yes, that's my understanding as well, but as I said it'd be nice if they actually fixed cover thumbnails on EPUB conversions at some point. (But I ain't holding my breath over here.)
