The Mobipocket Ebook format stores reflowable text in the Mobipocket format originally designed for Amazon Kindle devices, now largely superseded by KFX. Converting to RST produces a document file that stores data in the RST 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. This makes RST the practical choice when the destination system requires it or when the original format is not supported by the target application. 1converter runs this conversion on the server: your file is uploaded encrypted over HTTPS, converted using trusted open-source libraries, and the output is held for 24 hours before automatic deletion.
