I guess in future I'll have to stuff it in some web-accessible directory and load it via the builtin web browser. A bit of a drag...

Send to Kindle is the only way to get an epub into the Kindle mobile app. So you can't really sync between a Kindle device and the mobile app until you can actually get the book on the app.

I've just imported an epub into Calibre and sent it directly to my iphone kindle app and my kindle 7 (5th gen). I did go to Preferences/Sharing Books by Email and added EPUB to the two devices I'm sending to.

It worked. They both arrived but they are not properly formatted. There are a lot of symbols spread throughout the whole book. I then went back and converted the epub file to mobi. Then imported the mobi file and converted it back to epub and re-sent the second epub file. That worked and corrected the formatting too. No more symbols.

Is there an alternative way of correcting the formatting errors on the first epub file before sending so that they do arrive on the kindle without them? Or do you think Amazon will include any format corrections as part of the Send To Kindle process when it reaches the kindle or kindle app, without having to firstly do so in Calibre? Many thanks for any help.

Make sure your EPUBs are using utf-8 in order to avoid the funky characters. (Convert to EPUB -> Look & feel -> Text -> Input character coding: -> utf-8)

Otherwise, do what I do and convert to MOBI and then back to EPUB. Amazon does a garbage job of converting from EPUB format, so doing the EPUB->MOBI->EPUB removes all the fancy formatting that they can't handle. It's annoying but it works, as you've seen.

Try this simpler process:
- import epub to Calibre
- use the Modify ePub plugin to "Encode HTML in UTF-8"
- send email to one Kindle or app
- use the download option on the second Kindle or app to download the file

This saves you from double-converting, and also allows you to use whispersync since you only have one copy of the file in your Amazon library. If you do want to keep separate bookmarks on the two devices, then you would continue to email to them separately.

And remove all other formats and just leave it set to ePub.

Just no. Do not convert to Mobi. Use the Modify ePub plugin to set the ePub to UTF-8.

thanks, I just came on this forum to find a solution to this, and this works. Going to be a pain though. am I right in thinking this will only affect books that I find in epub as a book that I find in mobi would fix itself when converting from mobi to epub?

is there any harm in just selecting all in my book library and doing it all as one big batch?

Hi JSWolf
I'm sorry to have to ask but would you mind talking me through this please? I search, found and installed the Modify Epub plugin. Do I need to edit the plugin in or customise it in some way to set it to UTF-8. And do I just then import the epub file and Calibre takes care of things automatically.

I did try importing the original epub file again and sent it to my kindle. Still had the same funky characters and symbols within the text. So I imported the original file a second time and converted it from epub to epub and sent it to kindle and that seemed to correct it all. So I don't seem to need to convert from epub to mobi to epub again. Still have to do one conversion from epub to epub though.

Should I still have to do this if I've done as you suggested (which I don't think I fully have)? So how do I set the plugin to UTF-8 please. Sorry to be so obtuse.

Many thanks.

When you install the Modify ePub plugin, it adds a button to your toolbar. See first image below, last button on line 2. If you don't see this button, look for the 3 dots at the right edge of your main toolbar to expand the second line. Also make sure you've restarted Calibre after installing the plugin.

Once you've found the plugin button, go to the Calibre book list and select the ePub you just imported.

Click on Modify ePub. The second screenshot comes up. Check the box that you see I have checked. No need to select anything else. Click OK.

A job runs in the background and when it's finished, the message in the third screenshot pops up. Click Yes to replace the old EPUB file with the updated one. The original is saved as an ORIGINAL_EPUB file.

Email the updated epub file to your Kindle. If it looks o.k. you can delete the original_epub file.

CathyA,
Thank you SO SO much. Excellent instructions, so easy to follow and much appreciated. You guys are great.

Just one things, when I ran the Modify Epub and got the last screen shot, it replaced the Original-epub file in my library but left a copy of the original in the author's folder. I've deleted it from there.

Once again, many many thanks for your help (and JSWolf)

CathyA or JSWolf .... another little problem I need help on please.

So yesterday was happily using the Modify Epub plugin and sending epubs to my kindle and kindle app on iphone. One particular book isn't working though. I'm getting the standard email from Amazon saying it doesn't accept epubs but later says in addition it now accepts epubs. Don't think it's too big a file either as I presume I'd get a max size exceeded in the send process. Calibre says book sent.
So I converted the epub to mobi and sent it and that worked. Amazon also then sent me an email regarding from August can't send mobis any more. Any ideas why this one modified epub isn't sending? The only other thing the Amazon email says is to check the document isn't password protected or encrypted - neither applies. The book is The Brethren by Bob Woodward & Carl Armstrong in case anyone wants to try it. Many thanks in advance for any suggestions.

Something in the epub file is malformed. Unfortunately, Amazon doesn't tell you what caused their conversion tool to fail. You could try using Modify ePub to fix the manifest and TOC entries. If that doesn't work, then have Calibre do an ePub to ePub conversion and see if that fixes it.

tomsem · 06-28-2022, 01:56 PM

You might download Kindle Previewer app and feed the ePub to it. It might give you more details about what the issue is.

There is an epubcheck plugin for calibre
