Rakuten Kobo Inc is based in Canada, it is the most innovative EReader service which offers more than 50 million eBooks to customers spread across 190 countries and also developed a range of EReader that uses electronic ink screen to suits any readers style.
Although Kobo EReaders support a broad range of file formats such as Adobe PDF, Plain Text, HTML, JPEG, BMP, PNG, TIFF, and GIF for images, CBZ, and CBR for comic EBooks and also unprotected Mobipocket (.mobi, .prc) EBooks. They even support some formats, such as ZIM, unofficially.
However, in terms of features and user compatibility, we can say that EPUB and PDF are the most suitable EBook formats for Kobo EReader.
One of major the reasons why we can’t open Kobo files on other devices is they are DRM protected. In general, EPUB or PDF books with an ACSM file extension are protected by Digital Rights Management (DRM), the core purpose of DRM is to protect books from unauthorized copying. therefore Kobo books access is limited to Kobo App or an Adobe Digital Editions compatible EReader.
All Kobo EReaders share a unique paging system that gives users the ability to count and refer to the pages within each chapter separately, rather than the book as a whole. All Kobo EReaders require an internet connection during the initial setup phase and will only work when connected to Kobo servers.
