If you own a Kindle, you know the struggle: you downloaded a great book, but it’s in .epub format. When you try to transfer it to your Kindle, it simply doesn’t work.
While Amazon has started supporting EPUB via “Send to Kindle,” the process can be slow, buggy, and often messes up the formatting. The native, most stable formats for Kindle are still MOBI and AZW3.
So, how do you convert your files without installing heavy software like Calibre on your computer?
