e-pub > mobi azw3 on website linking +

olbeggaols · 04-03-2021, 04:29 PM

Hello,

I am a brand-new user of e-books, e-book readers, e-book editors and editing. I am using Windows 7 64bit; the Calibre for Windows 7 version; Sigil version 1.5.1
I am test uploading to Kindle (and, when they replace my defective one) Kobo both by way of a usb cable; both without any WI-FI or cloud storage.
At one point I thought I knew a lot about html, but Currently my site uses plain vinilla .html: no scripts nothing at all fancy and my knowledge has not kept up.

My question is about converting e-pubs to mobi and awz3, storing them on my server, and linking to them from the web content.

I have (I believe) read through the relevant sections of the user's manual. I do not see there the issue I seek help with. I checked through a few (5) pages of back posts and did not see this issue. So:

I use Sigil to create the e-pub format and open that in Calibre to convert.

The first thing I note is that the converted file is placed in a directory with an image (the cover image) and with an .opf file. The question is what do I store on the website? The directory, or just the .mobi file.
The second question is if it is the directory that gets placed on the website, how do I link to that?

I think I am asking: Is there any way that one file will serve?

The second question is that I seem to be getting two covers. I read the manual on this but it does not exactly apply to my case. I have created an image for the front cover because I wanted an all-text front cover with a boarder and the boarder never appeared properly from the .html output. BUT I have very similar text on my Title page. I suspect there is some confusion created by that. What I see as two front covers, however is the image, repeated twice. I see this in the reader in Calibre, but not in my Kindle. The question is: is this a problem? Will the output in the document downloaded from my site to someone else's Kindle show only one cover? Would it solve the problem to include the image in the text content and let Calibre find it by itself?

That is it for the moment!

Just the MOBI file. The cover and opf files are for calibre's use and are not needed for Kindle readers.

In my opinion the most versatile Kindle format is a Master MOBI created using Amazon's Kindle Previewer. That is a single file containing the older MOBI7 format and the newer KF8 (azw3) format, allowing pretty good rendering on all Kindle apps and devices. One advantage is that the user doesn't need to know which format to pick for their particular Kindle app/device.

Calibre can produce a similar MOBI-both format which is smaller in size, but I better trust the conversion by Amazon's tool to produce a file without any compatibility problems.

By default calibre replaces the cover image in the book with the cover set in the calibre library. Sometimes this does not work properly and can produce a double cover. That conversion option can be disabled ("Use cover from source file" option). Again, I recommend using Amazon's converter instead.

Hello Jhowell,

Thank you for this response. The Amazon Previewer looks interesting, unfortunately I am running Windows 7 and it only works for Windows 8 and above. ... I wonder, actually. I have installed programs supposedly for W8 and above and they work fine. I have 32G ram and the i7 processor, maybe that does it. Hmmm... an excuse to get that new laptop ...

Thank you for the information about how to link from my website.

Also thank you for the tip about the covers. I will try that.
