Resend Epubs?

DailyPlanet · 06-10-2023, 04:10 PM

My entire library is Epub, which over the years have always converted to mobi to send to kindle, so I can take advantage of whispersync and such. Now that epub covers are supported, would there be any advantages to resending my library with the original epubs? Mostly from Amazon saying the mobi format is outdated.

Yes. Custom fonts and the boldness slider would be available, to name two advantages. Also formatting is generally better.

This is send-to-Kindle, not Mobi vs KF8 from Calibre.

The principle is the same. AFAIK Amazon will convert epub to azw3. Previously the OP sent mobi files via the service.

I went back through my personal documents and re-sent them all as ePub so they'd get better formatting on my Scribe and I assume other Kindles and the apps when they decide to start sending KFX personal documents to them as well (wonder what they are waiting for).

In most cases these were ePub to begin with (from Tor and the like). I did 'upgrade' them to ePub3 first, and haven't had any S2K conversion issues with any of them.

Well, even if they never send KFX to any Kindle except the Scribe, KF8 still has better formatting than MOBI, so if I were the OP I'd resend my epubs.

So far it is all hypothetical: Scribe has been the only Kindle I've used since I got one. I do read with Kindle iPad but haven't looked at any of these on there to see if they look better.

I have an Oasis and sent a few epub as testers, both bold slider and alignment options are greyed out

That's interesting. Does Amazon convert epubs still to the old mobi format then?

I no longer have a modern Kindle to test myself, and when I had, I always sideloaded via USB to get the azw3 format.

Yes, and that does not enable bold slider etc. But I would need to test to be sure.

And then they tell their customers how mobi is an outdated format...

Really. I have few illusions left about Amazon, but I wouldn't have expected this.

I spake too soon, and was multi tasking.

Personal documents are KF8 (AZW3) for the most part (with bold slider). It may be that very old ones (sent before personal documents supported KF8) still are old mobi.

Alignment option is only available in KFX, the bold option should work if it is an KF8. If you don't have bold option, it somehow downloaded the old MOBI file. Try deleting one test personal document completely from the library, and resend the EPUB. Bold slider should show up, but left/justified won't unless you sideload them as homemade KFX files.

Thanks DuckieTigger for highlighting such a simple way for figuring out which of AZW, KF8 or KFX was actually sent to the Kindle for a given book. I used to rely on the presence or lack of cover in the library view (as covers used to not show up on KF8 files delivered via Whispersync), but this was fixed in a relatively recent firmware update.
