Common questions about converting EPUB to KEPUB
Is converting EPUBs to KEPUB safe with MConverter?
For cloud-based conversions, MConverter encrypts your EPUB files using the latest technologies, such as TLS 1.3 and HSTS. They are transmitted securely to our cloud service provider’s EU-based data center, which holds internationally recognized ISO 27001 and SOC 2 certifications. There, each conversion is processed in a separate, isolated environment. This technique further reduces the risk of a malicious file impacting other conversions.
Four hours after the conversion is complete, your files are automatically deleted from MConverter’s systems. You can also permanently delete your EPUBs and other converted files immediately after finishing the conversion with the trash icon.
When converting on-device, your files never leave your device. MConverter processes them locally. Note: on-device conversions are not yet available for some hardware-intensive formats.
For both cloud and on-device conversions, your files are never scanned or shared with third parties for marketing purposes.

Format description
KEPUB is Kobo’s enhanced version of the EPUB format for e-books. Its main use is for Kobo eReaders and Kobo reading apps.Kobo’s reading software treats KEPUB files differently from regular EPUB files, enabling Kobo-specific features such as improved reading statistics, faster page turns, better footnote handling, and its own rendering behavior.
To be correctly recognized as a KEPUB by Kobo eReaders, the file needs to end with .kepub.epub instead of .kepub. It’s also important to note that the e-book needs to be specifically converted with a tool like MConverter, as simply renaming a regular .epub file to .kepub.epub is not enough.
Note: DRM-protected Kobo books may fail to convert at the moment.
