Having your book work on a Kindle is really nice for beta readers. It’s also handy for proofreading your own books, since it feels more like a finished book.
It took me some time to dig up old forum threads about how to convert a PDF into a MOBI or AMZ file. Most articles say to download Calibre or other software, but I hate downloading software. Others say to use a PDF file directly, but the formatting is rigid and never looks right on a Kindle.
The best way is surprisingly simple. You can email your Word file to Amazon and they’ll convert it for you in a matter of minutes.

PS: I tried emailing a PDF file as they suggest, but I found the formatting always came out wonky, whereas Word files convert beautifully.
