Convert LIT to EPUB — Free Online Converter

LIT is Microsoft's discontinued ebook format, used by Microsoft Reader from 2000 to 2012. LIT files use a variation of the CHM (Compiled HTML Help) container with DRM support and ClearType rendering optimizations. Microsoft Reader was available for Windows, Windows Mobile, and Pocket PC devices, and LIT was the format used by early Microsoft ebook stores. When Microsoft discontinued Reader in 2012 and shut down the Microsoft ebook store, millions of LIT files became effectively orphaned — readable only through abandoned software. EPUB (Electronic Publication) is the modern international ebook standard supported by every major reading platform.

Converting LIT to EPUB rescues ebooks from Microsoft's defunct ecosystem and brings them into the universal standard that Apple Books, Kobo, Google Play Books, and hundreds of other reading apps support. This is a preservation conversion — saving content from a dead format before the last LIT-capable software disappears entirely.

Microsoft Reader is no longer available. Microsoft removed it from download sources in 2012, and it does not run on modern versions of Windows (Windows 10/11) without compatibility workarounds. LIT files are effectively locked in a dead ecosystem. Converting to EPUB is the only way to ensure the content remains readable on current devices and platforms.

EPUB is an ISO-recognized standard (ISO/IEC 23736) with guaranteed long-term support. Libraries, publishers, and archivists standardize on EPUB for digital preservation. By converting LIT files to EPUB, you move content from an abandoned proprietary format to an open standard with active development, broad device support, and institutional commitment to long-term readability.
