I always upload books to the Kindle via wifi. You email the .mobi version to youremail@kindle.com, within a minute you will get a verify email, where you have to click the link, then the file gets pushed to your kindle. I'm too lazy to deal with wires and stuff.

MOBI is so outdated and lack many newer features on Kindle. So much so that Amazon is discontinuing sending mobi via email later this year.

Wait what? Is that just mobi? Or can other files be used. My USB port broke years ago so I soldered on a qi charger and now just send books over WiFi.

They support sending EPUB now.

You can still use other formats on your Kindle. That restriction is for publishing new books on Amazon store.

If you want to publish a new book on Amazon, you have to use EPUB instead of MOBI. That's the only change afaik.

No, this applied to Send to Kindle service too. Announced a few days ago.

What are some of those missing new features when you use MOBI?

1. Can't choose custom fonts 2. Can't configure boldness

Maybe a few thing more, but these two are what put me off of using MOBI. (I believe there's a hack for jailbroken kindle to fix this)

That's too bad, the usb is broken on my old kindle, the experimental browser in it is too old to use to connect to the Calibre server feature and the only option I had left was sending mobi by mail. (It does not read epub) Can you think of any other solution ?

You'll be able to email Epub instead. You can already do it now actually if you send it as a ".zip" or ".PNG" but they reject ".Epub" outright. But they recently updated a support article saying send to Kindle will support Epub soon. Amazon converts it using their tools to their format that's right for the device.

Wait, do all Kindle models support epub reading ?

No none of them do. When you email an Epub file Amazon converts it using KindleGen to whatever your device supports.

Oh I did not know that thanks

Yeah the PNG trick works great. So great I don't understand they never made it official before

I used to do this but I realized how difficult it is to organize your books this way. Calibre → Kindle was a much better workflow in my experience.

You can also email epubs this way. You just have to rename them as .PNG because Amazon doesn't allow epubs. But if you trick it as PNG it forgets about this and converts it just fine.

Of course you can also convert with calibre but this method works well too.

Edit: oh apparently they support epub officially now. They didn't for a long time and the above workaround was great for years
