Quality of azw to epub conversion

Inquisitive_Ram · 07-31-2024, 01:24 PM

Out of interest, when people convert from azw to epub and then view on a kobo, is the quality of the resultant ebook as good in terms of formatting as the azw is on the Kindle?

Depends on what you mean by "quality" - different folks mean different things by it.

I do it all the time for AZW3 (DRM gone)
AZW can include other format types internally that might not fare as well.

One thing I found is KEPUB has issues with letter-spacing: <value>.
Spaces go away VISUALLY on the Aura2 and Libra2. I have a saved search to comment-out those lines in a CSS

What do you mean "they go away Visually"?

Do you mean the spacinglookslikethis with no spaces?

And you have to manually change the epub after conversion to correct it?

Nope. That's word spacing. Theducks meant l e t t e r s p a c i n g, which is sometimes used in books for a variety of reasons, most of them unnecessary.

If you mean azw3/KF8, I would suggest trying the KindleUnpack plugin instead of calibre's built in coversion to extract an ePub from an azw3 since the structure and CSS will be much closer to the azw3's structure (and much like the structure of the ePub used as input to Kindle Publishing). If you mean azw (mobi with DRM), then calibre' conversion is pretty much the only game in town.

Sirtel showed what it should be, but you show what Kobo KEPUB does

ChapterThree instead of Chapter Three

Stupid Vellum frequently has this in their CSS.

What? I've never seen this.

Do you send KEPUB or EPUB to your Kobo? EPUB is fine, but I like some of the other features, so I use KEPUB (after fixing the CSS)

One of the reasons I only use kepub for those few ebooks where I want to be able to zoom images or need a FLO ePub3 renderer is that the ePub renderer simply lacks quite a few of the display oddities that the webkit based renderer has.

Kepub on the Sage, epub on the Libra.

I actually checked a few kepubs on my Sage just now. Yes, chapter headings sometimes have no visible word spacing, but I couldn't see such an issue with body text. As I don't pay that much attention to headings (besides removing huge spaces above or under them), I've just never noticed it before. And I'm not going to bother with fixing it; let those headings run together, I don't much care. Now if I should ever see this issue with body text, it will be another matter.

The biggest gripe I have with epubs is that if they happen to be loooong books (as in multi-volume omnibuses), searching for a word or a phrase in them can be extremely slow. Kepubs don't have this problem.

Inquisitive_Ram · 08-01-2024, 03:57 AM

So if you send as an epub to Kobo do you not use the Kobo plugins or do you use them but set them up not to convert to kepub?

I never saw that used for other than Headings (tighten them a bit closer).

I tried them to space out *** breaks, but (old) My Astak (RMSDK) really did not like that (Calibre was fine)
