Kepublicity is a graphical application for turning standard EPUB ebooks into Kobo-formatted KEPUB files. It provides a simple way to prepare ebooks for Kobo readers without having to perform conversions from the command line.
The application supports both local conversion and direct device transfer. You can add EPUB files, process multiple books in a batch, and either save the resulting KEPUB files locally or send them directly to a connected Kobo device. Drag-and-drop support provides another quick way to add ebooks for processing.
Kepublicity uses kepubify as its conversion engine. The Flatpak build compiles and bundles kepubify alongside the application rather than relying on a separately installed copy.
This is free and open source software.
