About Converting LIT to AZW3
LIT is Microsoft Reader’s book format, an ITOLITLS container of LZX-compressed HTML related to Microsoft’s CHM help files. Microsoft Reader was retired in 2012, so the format is fully obsolete and nothing current opens it. When you need to move away from LIT, the usual reason is simple: discontinued in 2012.
Converting your LIT e-book to AZW3 solves that. AZW3 is Amazon’s Kindle format that succeeded MOBI, adding better typography and styling. It targets modern Kindle devices and apps. In practice you gain improved styling over mobi and optimized for kindle. PrivConvert runs the whole LIT-to-AZW3 conversion in server memory and deletes your file the instant the AZW3 is ready — nothing is stored, logged or reused.
When this conversion helps
- You need improved styling over MOBI
- You need optimized for Kindle
- Sharing a LIT e-book with someone whose software expects AZW3
Tips for best results
- Files up to 250 MB are supported, and you can batch-convert several LIT files at once; each is processed privately and deleted immediately.
