Kobo’s EPUB-derived e-book format optimized for Kobo reading features. Use this guide to decide whether to keep KEPUB or convert it for a different workflow.
PRACTICAL OVERVIEW

The right output depends on what must remain editable, how the file will be shared, and which application or device needs to open it.
FORMAT QUESTIONS
About KEPUB files
What is KEPUB best used for?
KEPUB works especially well for moving Kobo-oriented books into standard EPUB or printable PDF workflows.
What can change during conversion?
DRM-protected books cannot be converted and Kobo-specific reading metadata may be removed. Features that do not exist in the chosen output format cannot be carried across exactly.
Should I keep the original KEPUB file?
Yes. Keep the original until you have opened the result and checked its layout, quality, data, media tracks, or other important details.
