Yeah, that would really be great.

Just yesterday I wanted to order the new Kindle Oasis because I think the hardware is perfect (good to hold, physical buttons, …) but was told by a coworker just before ordering it can‘t open .epub files.

Edit: Thanks for all the tips about .epub + Kindle. I just found out that there also is an option to install Software like KOReader[1] if one wants to go the Jailbreak route.

No Kindles can, they're based around Mobi, which is a quick file conversion away from an epub.

It's quick to convert but I've had varying results going from epub -> mobi, especially with calibre. What's worked for me the best has definitely been kindlegen but it's still not perfect.

In the Calibre settings, did you specify the exact version of the Kindle you have as the output device? With that set correctly, and not just left as the default, it has been years now since I had any formatting issues going from epub > mobi/azw to read books on my Kindle Paperwhite.

Thanks, I actually don't think I've done this so I'll give it a shot!

It's easier to just buy a device (literally all other e-readers) that support standard EPUB files out of the box.

Calibre (https://calibre-ebook.com/) is great for converting epub to mobi.

Can't you email the .epub files to your kindle and it opens them?

I was doing this with a Kindle Paperwhite.

It does this by converting them to AZW3, which can have poor results or fail entirely for long books, books with lots of images, or books with certain formatting.

I was just reading about a couple of ereader apps this morning.

and a newer one that the developer just announced in a Reddit rust group:

I would love to buy some e-reader with koreader already installed, I don't think it exists yet
