I came across the Web Books Viewer, which can read EPUB and WEBZ formats offline. I understand that it doesn’t require traditional installation, but I’m unsure if this works seamlessly on both desktops and mobile devices. Specifically, I want to know if it’s possible to use the viewer offline on my Android device, and if I need the Chrome browser installed for that. Also, are there any limitations when using it offline, like functionality with annotations or bookmarks?
