LIT is a ebook format: it stores data in the LIT format. WPS is a document format that stores data in the WPS format. This converts the reflowable ebook layout into a fixed-page document format. Metadata such as creation date and embedded colour profiles is preserved where the target format supports it. Converting between these two formats is common when the source application does not support WPS natively or when the target platform only accepts WPS. 1converter processes this conversion server-side using open-source tools.
