2025. Calibre improves support for Kobo e-Readers



Library organizer software Calibre has released a new version 8.0.1 which boasts improved support for Kobo e-readers. Calibre can now natively edit, view and convert Kobo’s proprietary KEPUB file format to regular EPUB files for reading on non-Kobo devices and apps (like Calibre itself). Additionally, users of Kobo devices can now use Calibre to convert EPUB to KEPUB automatically when sending books across, saving time and hassle of first converting and then sending. Besides, Calibre can now connect to folders and treat them as USB mass storage devices. That might sound odd, but according to Calibre, this is especially useful if you're running Calibre on a Chromebook. That's because Chrome OS treats external USB drives as folders.

Spell check now allows to exclude words in ALL CAPS or with numbers or in camelCase/snake_case from the list of words. The search now allows easy inverting the current search via the right click menu on the search box.
