Nice tool. I thought kindle files were mobi? Any difference?

LiberatedLlama 6y ago
There are a few "kindle formats"; the most basic of which are just mobi files. Generate a mobi file and any kindle should be able to load it fine.

Kindle has jumped around in formats over the years. It's been AZW (which is basically mobi), AZW3, and now KFX. I assume that KFX is what this tool is calling "Kindle".

  It currently does AZW3 for kindle, but I will add in the sub option to choose from those three formats.

    Oh, that option being listed as "Kindle" is just there so people don't need to understand file formats currently? :D

      just about, trying to make it easy to understand

The ones with DRM are .azw, basically an encrypted .mobi. Calibre is your friend. https://calibre-ebook.com/ https://calibre-ebook.com/

  And (another fun fact) if you want to email EPUBs to your kindle, just make the file extension .png (!?) and it will be automatically converted, without the need for Calibre.

    Really!? This is the best tip I've heard in years. This will save me a lot of time when on the go (without access to calibre)

    Although who knows why you'd want to go without Calibre when it's so multi-functional?

      Most people HN would want it since we are power users who like desktop apps. But don’t rob yourself of trying to understand why everyone else doesn’t want to use desktop software to get a book on their Kindle. For example, my girlfriend is an avid ebook reader but couldn’t be less interested in it. “I can see why that could be useful but... no thanks.” We like the smell of our own farts too much sometimes. In this case, in the form of “why don’t people want to use more software to do what you were already doing without it?”

        > But don’t rob yourself of trying to understand why everyone else doesn’t want to use desktop software to get a book on their Kindle. Yes, that's a good point. I originally had "Why would you want to go without Calibre when it's so multi-functional?", but changed it to "Who knows why you'd want …" in an aim to sound less confrontational. I seem instead to have gone the other way!

      I can download an epub on my mobile. I can email an epub from my mobile. I can't run calibre from my mobile. I can rename .epub to .png and email that from my mobile. Yes, I can host calibre somewhere else. No, my technologically savvy friends and family cannot. I also don't want them to depend on me to be able to convert an epub for their kindle when there's a trivial solution that doesn't require additional dependencies.
