Convert your EPUBs to XTC to preserve their formatting

While getting e-book formatting to match what you'd find in a printed book has always been a challenge, the native software that ships with all Xteink devices handles it particularly poorly. While you certainly can read EPUB files loaded onto them, they may show up with awkward formatting, such as unnecessary spacing between paragraphs or missing indents. Heck, these devices still can't display text in bold or italics, never mind if you're reading something with embedded charts or images. You can solve for this by converting your books to a proprietary format called XTC before loading them onto your e-reader. Rather than a free-flowing text document, an XTC file is essentially a series of bitmap images of the original e-book.

All images, stylized headers, and text formatting will thus be preserved, with a few downsides: The image can look slightly less crisp, and the file will be a lot larger—50MB or more, depending on the book, versus 2MB or so for most EPUBs. There are a few ways to transform your EPUBs into XTC files, but the easiest is this web converter, which allows you to customize the font choice, page orientation, text alignment, and other factors, then download the finished result to sideload onto your device.
