What LIT is

Microsoft Reader was an early ebook app, and .lit was its format — a packaged, reflowable book based on Microsoft’s e-book technology. Some titles included DRM that tied them to the Reader software.

Microsoft discontinued Reader, so .lit is no longer actively supported. Books in this format are leftovers from an earlier era of digital reading.

Reading LIT today

To open a .lit on a modern device, convert it to EPUB with an ebook tool, provided it is DRM-free. DRM-protected .lit files generally cannot be converted.

Ebook files are small, so storage is never the issue. The reason to convert is simply that current readers no longer open the LIT format.
